Bonnie Bramlett co-wrote this song with Leon Russell in 1969. Delaney Bramlett, Bonnie's then husband and musical partner, was originally credited as well, but it appears the bulk of the composition was by Bonnie and Leon. (I'm seeking clarification, as I've read articles that have said all three of them wrote it together, and others that said that only Leon and Bonnie, or only Leon and Delaney, composed the song.)
She introduces the song here with part of Leon's "A Song For You" then launches into a long, torchy, emotional salute and send-off to her dear friend at his Tennessee memorial ceremony (there was another memorial service in Leon's hometown of Tulsa as well).
