Complete digital audio bootlegs of Ray Charles' Austin City Limits TV concert, originally taped on October 23, 1979, have been circulating on the web since the late 1990s. For free, in a very decent quality. It's still easily and freely available through torrent websites.
Nevertheless, Hi Hat, an obscure British-Cypriot record label, found a reason to issue the concert on CD (announced as a "remastered, unofficial release"). For an indiscernible reason, the majestic version of Oh, What A Beautiful Morning was mutilated.* The least essential information I aggregated in this article and on this page was used for the liner notes.**
Ray Charles - Live Austin Texas '79. Hi Hat HHCD3059, July 22, 2016. In Europe also streamed on Deezer.
A second release, its text-less cover illustrated by a moron, also from last year is: Ray Charles - Live At Klru Studios, FM Broadcast, Austin Tx, 23rd October 1979 (Remastered). Groove Dust, November 15, 2016.
