Has anyone mentioned the obscure album by Sleepy Hollow
on the Family label, 1972 or so?  that is the most late-period
Beatlesque album I've ever heard, and several songs on it
are excellent.

The most early-period Beatlesque album I've ever heard is
the self-titled album by Liverpool Echo, which has just
been reissued by Rev-Ola.   It's also very good.

You aren't going to find anything that resembles the fab
four more than those two records.
