1st post should have opened with: Bill Porter was a genius.

Bob: Burgie's Euro-American interpretation of Choucoune is musically faithful to the Creole original both he and Franz Casseus (guitar) had already covered. Please do post it here if you find the Belafonte-Yellow Bird reference.

I bring up this 45 as the OP didn't mention which CD track(s) were of interest. The LP credits may or may not help. I've been asking 'Who are those guys?' pretty much since it came out. Btw the Euro was on London (LED 232.)

I've always pegged the A-side as more Norman Luboff/Richard Vaughn inspired (the latter was Arthur Lyman's engineer.) Before he left RCA Bill Porter engineered Chet Atkin's take on Yellow Bird in '62. I think Atkins' last cover was in '69 under Nashville String Band with Henry "Homer" Haynes and Kenneth "Jethro" Burns not too long after Paul died.

Re: The youtube link above, the Kingston Trio also did not cover Yellow Bird (Yes, we have no banana?) You're hearing The Brothers Four on track #1.

All apologies for threadcreep but... "Who are those guys?"
