Happy Head Back Of My Cab Lyrics

(Carl L. Marsh)
kevin the coma he was a smart one
but even so there were things
  he didn't understand
peter the powerdrain
  he's been around again
looks kind of sickly
  from breathing the fumes
maybe on second thoughts
(From: http://www.elyrics.net/read/h/happy-head-lyrics/back-of-my-cab-lyrics.html)
  he doesn't understand too
kevin and peter  peter and paul
matthew mark luke and john
  i've had 'em all
in the back of my cab there's room
  for everybody
i've had 'em all
  in the back of my cab
