That site parrots data first published in one of JAT's session books, regarding the January 10-16, 1970 rhythm section rehearsals for the January 26, 1970 OS at the International Hotel in Las Vegas. Whether the author was privy to actual recordings or simply paper documentation is unclear.
Since RCA Hollywood had professional recording capability (i.e. sessions for "G.I. Blues", "Burning Love"), it is more than likely some recordings were at the very least made of the "new" songs being worked up, to judge their merits. Glen Hardin was crafting some arrangements. In any event, none have ever surfaced.Outside RCA Hollywood, January 1970Note: friend Jerry Schilling behind Elvis
