The Original Delaney & Bonnie, also known by its subtitle Accept No Substitute, is the second studio album by American recording duo Delaney & Bonnie. It was recorded with many of the "friends" that would form the core of their best-known 1969–70 touring band, including Bobby Whitlock, Carl Radle and Rita Coolidge.

Robert Stanley Whitlock is an American singer, songwriter and musician. He is best known as a member of the blues-rock band Derek and the Dominos, with Eric Clapton, in 1970–71. Whitlock's musical career began with Memphis soul acts such as Sam & Dave and Booker T. & the M.G.'s before he joined Delaney & Bonnie and Friends in 1968. His association with Delaney & Bonnie bandmate Clapton led to Whitlock's participation in sessions for George Harrison's 1970 triple album All Things Must Pass, in London, and the formation of Derek and the Dominos that year. On the band's sole studio album, the critically acclaimed Layla and Other Assorted Love Songs, Whitlock wrote or co-wrote seven of the album's fourteen tracks, including "Tell the Truth", "Bell Bottom Blues" and "Why Does Love Got to Be So Sad?".
