From the wiki: “‘It Don’t Matter to Me’ was written by David Gates. It was first recorded for the eponymous debut album of his group, Bread, and released as an album track in September 1969.
“In 1970, during sessions for Bread’s second album, On the Waters, Gates had the group re-record ‘It Don’t Matter to Me’ for the group’s follow-up single to the #1 hit ‘Make It With You’. (The re-recording, however, was not included on the second album.) Released as a single in September 1970, this new version hit the Top-10 in both the U.S. and Canada, peaking at #10 on the Billboard Hot 100 and spending two weeks at #6 in Canada.
