Supergroup?
Davie Blood: co-founded the Curds.
He began backing harmonies on cover songs like "Churn! Churn! Churn!", a cookbook cribbed folk number they turned into a number 1, but after their frontman's departure led to the Rolling Stone cover quip Does This Bury Them?, Blood would continue just long enough in the group to compose and sing lead on the iconic version of "Six Feet Deep", which has been covered by other artists on major labels over twenty times.
Stevie Sweat: co-founded Ruston Proctor.
He wrote and sang & played lead vocals & guitar on their biggest hit, "What do I know?" The song has been licensed and used in countless films about the Vietnam War, even though the author of the lyrics has stated he doesn't know what the song is about. The band survived absences by all their members save for Sweat.
Willie Tears Graham: co-founded the Buddies.
Out of all the previous bands, this is the hit machine, albeit primarily in Tears' native UK. Nevertheless, their first top 10 single, "Train Station", would chart at 5 on both sides of the Atlantic and lead Tears to co-author their follow-up number 2, "Station Station Station".
McNeil Urine: co-founded Ruston Proctor.
Urine is the most successful of the group in the music industry by critical and commercial standards. By the time he joined the first three, he had already made a name for himself, both as a solo artist and on his albums with Insane Animals.
If Blood, Sweat & Tears weren't a supergroup already, adding Urine to the mix would put them over the top. Although he only joined his former Ruston Proctor bandmate for one album, 1970's À la Carte, it's outsold all their others to date, solo or otherwise.
