What a pleasant little surprise. This is a demo tape for a song that was never put on any of their albums, but was given to Billy J Kramer and the Dakotas (it was a substantial hit for them in 1963). As I recall it (I mean, I wasn't there in the studio at the time, I mean as I recall from what I've read... oh, you know what I mean), Brian Epstein would sometimes ask Lennon and McCartney to give a song to a new group he was trying to launch. Because they WERE John Lennon and Paul McCartney, the boys would usually have a backlog of songs that they felt weren't quite their best or were too much like another song they were pushing, whatever. And even the lesser Beatles song of that day were as good or better than what other artists were putting out.

Yet they lived out their dreams and really did become the most popular musical influence of their era. This song has that cheerful (almost naive) energy. It's wonderful little echo of a time long gone and not likely to ever recur.
