Kelvin Tan Wei Lian (陈伟联, born 5 October 1981) is a Singaporean former Mandopop singer who earned a living as a busker before he won the first edition of Project SuperStar in 2005. He has released three albums, All I Want Is... (2006), i-Weilian (2007) and Moving Notes...Kelvin Tan (2009). He also had a solo concert at the Singapore Expo, lead a choir at the opening ceremony at the 2008 Summer Paralympics, and singing Singapore's 2009 National Day Parade's theme song.

Born blind due to Leber's congenital amaurosis (which causes the retina to disintegrate), Tan grew up listening to 1980s Mandopop ballads, which inspired him to learn to play the piano and guitar. He studied at the Singapore School for the Visually Handicapped and Dunearn Secondary School.^[1] After his O-Levels, he worked as a massage therapist and a singer at a café. He also busked at Jurong East and Waterloo Street, playing his guitar and singing Mandopop ballads for two to eight hours per day.^[1][2] According to The New Paper reporter Mindy Tan, his performances drew large crowds (including Malays and Indians), some of whom were so "impressed [by] his music" that they would "sit on the pavement nearby for up to an hour listening to him".^[3]

Tan and four blind friends auditioned for the inaugural season of Project SuperStar, but only he was accepted as a contestant.^[1] Throughout the competition, there was extensive debate over whether viewers were voting for him out of sympathy and whether a blind man who could not dance deserved the title. Further controversy arose when his home address was posted online and fans offered him sex services.

Tan emerged as the male champion and entered the grand final against female champion Kelly Poon. The judges gave Poon more favourable reviews, but Tan garnered 64% of the 533,000 telephone votes. Both finalists also released limited edition singles; Tan's cover of Fairytale (童话) by Michael Wong sold 12,239 copies, while Poon's cover of Lost Goodness (遗失的美好) by Angela Chang sold 11,319 copies.^[4] Thus, Tan became the grand champion and was awarded a recording contract with Play Music.^[5]

Tan's debut album All I Want Is... (我只是想要), which contains four original songs and all of his famous competition recordings including Fairytale (童话), Matchstick Heaven (火柴天堂), Heaven Knows, 其实你不懂我的心, etc.,^[5] was certified platinum in Singapore within five days of its release.^[6] Its title track topped the Singapore music charts in February 2006,^[7] while another of its songs, Touch (触摸 ), won Best Theme Song at the 2006 Star Awards.^[8] The debut album also had another TOP chart hit 爱恨难.

In 2007, his second album, i-Weilian (i伟联), was released and the song Ordinary Man (普通的人) topped the Singapore charts that October.^[7] Besides Ordinary Man, I Love You also hit Number 1 regionally in the Global Music Chart, which consolidates chart results from Taiwan, Hong Kong, China, Malaysia and Singapore. His 3rd single, 亲爱的请做个好梦, from the album also hit TOP 5 in Singapore's YES 933 醉心龙虎榜 chart. This album eventually sold 15,000 copies in Singapore and 20,000 copies in Taiwan.^[1]

In 2009, he was selected to sing Right Here (就在这里), the Mandarin version of the National Day Parade theme song What Do You See?,^[12] and four years later, he sang a tribute song to Singapore named Treasure Every Moment.^[13]

In July 2017, Kelvin released brand new Mandarin album 新谣 (The Singapore Songbook),^[14] which is a tribute to the heritage of local writers and compositions in Singapore. In it, Kelvin interprets household classic tunes from the 80s, 90s and 00s; including Liang's Friendship Forever (细水长流), 夜的眩晕, 让夜轻轻落下, Dick Lee's Home, Roy Li's 等你等到我心痛, Eric Moo's 你是我的唯一, 情谊藏心里, among others.^{[14][citation needed]} The album was released digitally only and topped the charts at iTunes.^[14] The album design was also conceptually done by Singapore renowned artist 阿果.

He acted in the getai movie 881 and several television serials (notably The Dream Chasers), winning Most Popular Newcomer at the 2006 Star Awards.^[2][8] However, he declined further roles, describing acting as "not [his] cup of tea because there's nothing else [he] could act as except a blind man".^[5] He also participated in variety television shows in Singapore (notably as a guest judge on Campus Superstar) and Taiwan (such as Happy Sunday), but some Taiwanese hosts rejected him over fears that their jokes would offend him.^[1] Another controversy arose when he was a contestant on the Singapore Mandarin edition of Don't Forget The Lyrics, as netizens were concerned that being unable to see the monitor would disadvantage him.^{[citation needed]}

In 2015, Tan represented Singapore in Goalball at the 2015 ASEAN Para Games held in Singapore.^[16]
