Hi jbaent, yes could be, or a pressing-plant missprinted version. I have seen another Warner-Bros-LP-Sampler which features various WB-Artists. That record was a regular sampler-record, not a promo, and it has a yellow cover carrying the same Bugs-Bunny-artwork. It can be found on the
www.45worlds.com record-collectors site on the various artists column.
I can remember, that there was an old vinyl-bootleg with different cover-artwork and that record carries the wbms cat-nr. as matrixnumber, but i cannot recall the exact title of the bootleg-lp. The content is the same concert, as on the Warner-Bros-Promo-LP.
PS: There is also a BBC-Transcription-Record with Dire Straits and The Motors on it, and a 2-Record-Set with Dire Straits and Phil Collins. These two records are currently on my want-list, but there is also a Bootleg-BBC-Record with Dire Straits and The Pretenders. The genuine BBC-Records have a white-lightgreen-label and the Counterfeit-BBC-record has a white-black-label.
