Its not really a Halloween song, but I love Werewolves of London.
AAHHOOOOH!!!!
In the late 70’s I was on a business trip in Fort Lauderdale and went to the Bahia Cabana bar on A1A on a Halloween night. I played Zevon’s record and got the bunch howling. We must have played it dozens of times and howled for hours. Something I’ll never forget.
