In 1975, The Doobie Brothers hit the top of the charts with "Black Water"!
The song was from their 1974 album "What Were Once Vices Are Now Habits," and was the first of two No. 1 hit singles for the band. "Black Water" was a B-side for the lead single "Another Park, Another Sunday," which peaked at No. 32 on the Billboard Charts. Although, Tom Johnston was the lead vocalist in the group, the song's writer, Patrick Simmons sang lead on the song.
The Doobie's second #1 would come much later in the form of the Kenny Loggins assisted, "What A Fool Believes," sung by Michael McDonald, which again shocked the band by it's success as the band found out about the song rocketing up the charts when they came back from tour overseas.
