Ray Charles In An Early Seventies Concert

Episode 2 of Tony Palmer’s series The Story Of Popular Music, titled God’s Children – The Beginnings, has a rare color sequence, where Ray Charles and his keyboardist John Henderson deliver part of a concert’s finale.
The footage is most probably from 1972, and may be related, somehow, to Gary Keys, who also claimed directing the failed documentary Soul Of The Holy Land – The Lost Concert.
Charles was also featured in part 5 of the series (Who’s That Comin’ – Blues), but I haven’t been able to check that episode yet.
