When the Beatles played historic Carnegie Hall on 12-FEB-1964, the
opening act was a folk group named the Briarwoods. I have the names of
two members of this band, Paul Zlotucha (drums) and "???" Beach (banjo).

I'm looking for the complete Briarwoods lineup with names and
instruments played. Reliable reference must be included.

You could try asking Zlotucha's son:

Thanks, I've already sent Paul Jr. an email. RobertSkelton, are you
the same person as Paramucho (from rec.music.beatles)?

BTW the banjo player's name is Stanley Rufus Beach.

I'm not Paramucho - in fact I don't even like the Beatles that much,
I'm more of a Stones fan. Good luck with your quest.
