I just found this great clip of the feelies performing "Doin' It Again" on Letterman. It looks like only three actual feelies were present (Mercer, Million and Weckerman), but what makes it really interesting is that it reunites them with Crazy Rhythms-era drummer (and Letterman band member) Anton Fier. [As a poster pointed out, Anton Fig, not Fier, is Letterman's drummer.] I vaguely remember watching this at the time.
If you haven't seen it already there is also an awesome version of "Crazy Rhythms" up on youtube where they look to be playing at a hippie/nerd alliance conference circa-1979. Check it out. This is a real treasure.
Tomorrow I will post a song in honor of this blog's very first poster, "secretchimp."
