“‘The Heart That Makes Me Whole’ took more work than anything else we ever wrote. In the end, his verse and bridge lyrics are almost exactly what he sent me the first day except a small change here or there, and I came up with the title line ‘The Heart That Makes Me Whole’ after the first one didn’t sing quite right. Every song got auditioned by Dan Penn for this album. I didn’t tell him who wrote it or when it was from, so each tune was chosen on its own merit. I had really hoped that Leon would be on the session playing organ with us but sadly, he passed before we recorded and it was a little bitter sweet not having him with us.
