Continuing conversation with Daryl in this section
No problem, colonel snow. I believe that the William Morris contracts were for other musicians and backup vocalists as well besides Burton and Guercio. It would seem that Elvis had to come to an agreement with the hotel via the William Morris Agency as well. I know I've seen WMA contracts for people such as John Wilkinson, the Sweet Inspirations and J.D. Sumner & The Stamps for various tours / engagements pop up from time to time on either eBay or via an auction. Those William Morris Agency agreements were between Elvis' management and the respective independent artist. I don't have very many of those type of contracts, though I do have a copy of the one that Elvis signed in April, 1969 for the first Las Vegas engagement at the International Hotel. It is also signed by Alex Shoofey. The only reason I have that contract is because I don't have AFM documentation at the present time pertaining to the recordings RCA made in August, 1969. I do have copies of all the RCA recording pages pertaining to those live recordings, so it's not as though I don't know who those musicians & backup vocalists are. At one time I contacted the local in Las Vegas and they told me that they don't have anything prior to 1970; it would seem that in late 1969 (presumably November), members of local 369 voted on a referendum that all members would participate in a health & pension welfare fund, which was approved. I do have plenty of AFM documentation for most of the other Vegas engagements afterwards, though there are a few years where I don't have quite as much, such as 1971 and 1974. For many of the Las Vegas engagements, I have documentation not only for Elvis' rhythm section but also the members of the Bobby Morris Orchestra & the Joe Guercio Orchestra. To give you an example of what I mean, there was a thread over on FECC many years ago in which DJC claimed that the guitarist that played the great solo during the December, 1975 soundboard recording found on "Dinner At Eight" was not Tony DiCaprio. I have the Orchestra Report for both weeks of that engagement and he is listed for both weeks. If I recall correctly, he also was there in December, 1976 as well.
Now, as for Lake Tahoe, I have some documentation pertaining to those engagements but for some reason the documentation I have only lists Elvis' rhythm section, Joe Guercio and the orchestra contractor, Al Tronti. It doesn't actually specify who the members were in the Al Tronti Orchestra.
I should also point something else out as far as payments by the record label. No label is perfect and they do make mistakes. I've seen some documentation where the wrong individual was paid for work someone else did. I don't want to get into specifics but basically, in this instance the recordings came out several years after Elvis died but he didn't begin working for Elvis until a few years after the recordings were made; yet he got compensated for them.
