Not a 1967 release - the bulk of the album is the 1967 US album THE SOUL OF A BELL on Stax, but the new title track here, "A Tribute To A King", a memorial to Otis Redding who died in December 1967, wasn't released in the States until March 1968, and entered Melody Maker's top 30 in the week of 8th June 1968. Also, the fact that this is on Atco rather than Stax indicates that this is a post-May 1968 release, after Stax had moved to Paramount/Dot (represented by EMI in the UK), whilst Atlantic/Atco retained the back catalogue. I'm having trouble finding an exact date for this, but I'm inclined to think 1968, as the previous number, 228002 THE BEST OF KING CURTIS, is in this site as a 1968 release.
