Ray Charles On Rock & Roll Remember Radio Show (1983)

According to this contract, Ray performed at two broadcasts of Dick Clark's NBC (American) Bandstand, on 10 and 12 April 1957.
[There's always some reason to doubt the authenticity of this kind of documents, but this one looks genuine; it was recently sold for $216]. The contract above was signed by "the other" Ray Charles Offenberg.

The 4-LP set above contains a 4-hour recording of Dick Clark's Rock & Roll Remember - Radio Show, including the original program segment sheets, from 21 May 1983 (radio shows were still archived on wax or vinyl at the time). The year 'remembered' in this show was 1959.
Ray Charles' music was featured with several tunes, spanning his music output from the mid 50s to the mid 60s, and with a series of interview sequences. I guess this interview took place for this occasion, in 1983.
I haven't been able to verify it, bur after Clark's passing, Jerry Waxman wrote that "[Clark] was the first mainstream jockey on a commercial station to play Ray Charles (Hallelujah I Just Love Her So)".
