From the wiki: “‘Tell the Truth’ was composed primarily by keyboardist Bobby Whitlock, with guitarist Eric Clapton adding the last verse. As admirers of Sam and Dave, Clapton and Whitlock styled the song as a ‘call and response’ with the pair singing alternating verses.
“The original version of ‘Tell the Truth’ was recorded in London on 18 June 1970 during the sessions for George Harrison’s triple album All Things Must Pass. Four days before the session, Derek and the Dominos, with Dave Mason as second guitarist, had played ‘Tell the Truth’ at their debut concert, held at London’s Lyceum Ballroom.
