Peanuts "It's The Great Pumpkin, Charlie Brown" (Charlie Brown Records, 2604, 1978)
Amazingly not available on CD (though throughout the '70's it was released on vinyl in a variety of formats; long playing 12", book & record 7", etc), this is the shortened-for-LP adaptation of the beloved Halloween special from 1966. Recently the subject of a "making of" book (and readily available on DVD), its return to the yearly Halloween television lineup was always welcome for me as a kid (well, aside from all of that "World War I Flying Ace" stuff which just made me impatient for the most part). Just like tons of kids I can remember liberally quoting the "I got a rock" line while Trick or Treating, and the less said about the time I tried to cut up one of my bedsheets in an attempt to emulate the ghost costumes worn by many of the characters the better.
