Thomas first attracted interest in his work as an accompanist with Donald Byrd and Cannonball Adderley, before working as a session musician in Memphis, Tennessee, and releasing singles on the Goldwax Recordslabel. He had little solo success until he moved to Glades Records in Miami, Florida, and in late 1972 he released "Why Can't We Live Together". The record topped the U.S. Billboard R&B chart, made the top three on the BillboardHot 100, and top 20 in other countries including the United Kingdom where it peaked at #12 on the UK Singles Chart. This disc sold over two million copies. He was earlier part of a group called Phillip & the Faithfuls, which also included the singer Phillip Reynolds, releasing material for the Goldwax imprint, including "Love Me", "What'Cha Gonna Do" and "'If You Love Her". He then became a session musician in Memphis, continuing to release solo sides for Goldwax, including "Have Some Boogaloo". He also released "It's My Life" in 1967. In 1970, he had switched labels to the Climax imprint and one side called "What's Bothering Me". Relocating to Miami, Florida, in 1972, Thomas played sessions for the TK group labels, signing to the Glades Records imprint, where, later that year, he released "Why Can't We Live Together". Thomas followed up the release with "People Are Changin'" which reached the charts in 1973. In 1974, he released the albumYou're the Song I've Always Wanted to Sing. He went on to release six further Glades singles and then, in 1975 recorded a duet with Betty Wright entitled "It's What They Can't See". From 1976 through 1980, Thomas recorded singles for both the Glades imprint and the T.K. Disco label, including "Stone to the Bone", "Africano", "Touch to Touch", "The Magician", "Freak In, Freak Out" and "Drown in My Own Tears" and the albums The Magician and Touch to Touch. He also continued to work on sessions for TK Records artists, including Gwen McCrae, and in later years as a producer. Thomas went on to record several R&B hits culminating in "Gotta Give a Little Love ", a U.S. top 30 soul entry in 1984 for Gold Mountain Records. Thomas appeared on Nicole McCloud's 1985 albumWhat About Me?, singing on a duet with her called "New York Eyes". This track reached #41 in the UK. In the 1990s, he worked as a producer for LaFace Records and released the album With Heart and Soul for DTM Records. Also, his song " To Hold You" was a massive hit in the Philippines, and gained further popularity in 2017 when it was covered by Darren Espanto for the film All of You. In 2015, Drake sampled Thomas' signature hit, "Why Can't We Live Together", on his single "Hotline Bling".
