I grew up in the 70s, the era of bad clothes, awful decorating, and bubble gum rock.
My "most embarrassing songs" include (but aren't limited to!):
Donny Osmond, "Go Away Little Girl" and "Sweet and Innocent"
The Osmonds, "Yoyo" and "Love Me for a Reason"
Tony DeFranco, "Heartbeat It's A Lovebeat"
The Archies, "Sugar Sugar"
The Partridge Family, "I Think I Love You"
Shaun Cassidy, "Hey Deanie" and "That's Rock and Roll" (unlike Leif Garrett, he could really sing!)
Rick Springfield "Affair of the Heart" and "Don't Talk to Strangers"
Actually, I wouldn't turn any of these songs down; I'd just roll up the windows!
