I have a 45 from 1968 with picture sleeve, and on it is comedian Milton Berle singing The Beatles’ “Yellow Submarine.” My copy is a DJ copy, but could you please let me know if this single was sold in stores or was it just for DJ use? If you should have any more info on this single, I would appreciate it. P.S.: I have every Beatles tribute album and CD, and this version of “Yellow Submarine” is not on any of them. ►
