In the very early 70s, my sister was just becoming a teen, and she always wanted to have music on in the car when my family was on one of our very frequent road trips. My dad, the old Scotsman, was always about, "can't we just have peace and quiet?" My sister would get all sulky, so he would invariably let her have her way on that one thing. He hated most of the AM hits (KDWB 63) but one thing my entire family sang along to was "Bad Bad Leroy Brown."
I think we sung, "baddest man in the whole DARN town," though. I'm not positive about that.
