According to a posting on the FECC messageboard the next release from Straight Arrow, scheduled for early May, should be an previously unreleased recording of Elvis' Las Vegas Dinner Show from September 3rd, 1973.
From the posting:
It is very strong concert, containing the only known 1973 version of "It's Now Or Never", rare "Polk Salad Annie" performed only twice in 1973, part of "Jailhouse Rock" and for 'rare live excerpts' fans there are bits of "Guadalajara", "Miracle Of The Rosary" and "Farther Along".
This show was recorded by the same person as Dec. 02nd, 1976 concert and once again for our CD release, an original master tape will be used. The sound quality is excellent - regarding the off-line source.
Note: to prevent any speculations, we would like to make clear that the CD "Top Acts In Vegas Vol. 4" from 1995 is containing September 2nd, 1973 Dinner show, NOT September 3rd, 1973 Dinner show as stated in the CD design. The date is wrong.
