Some of my favorites include:
The Life cereal commercial with Mikey in it.
"Let's get Mikey to try it! He won't eat it! He hates everything!" "He likes it! Hey Mikey!"
The Purina Cat Chow commercial?
"Purina Cat Chow, chow-chow-chow?"
The 9-Lives cat food commercials with Morris in them?
"Morris! Time for din-din!"
And of course all those 7up commercials with Geoffrey Holder in them.
He was more of a two-hit wonder, as eight years before "Drift Away," he had a hit with "The 'In' Crowd."
Another song that I don't think hasn't been mentioned yet is "Shattered Dreams" by Johnny Hates Jazz. I don't know why they had another hit?
If the commercial is for Minute Maid orange juice, the song is "Limbo Rock" which was originally done by Chubby Checker.
Of course the song in the Tropicana commercial for its similar product is Olivia Newton-John's "Physical"?
I suppose no one has mentioned BTO (Bachman-Turner Overdrive) yet? After Randy Bachman left, they were simply BTO (although drummer Robbie Bachman remained in the group)
Also, the Bay City Rollers were sometimes referred to as the BCR's?
There are some misheard lyrics in "All Along the Watchtower" that can be X-rated, but I don't really think that's the case.
However, the album cover as released in England and other places outside the US has a lot of naked women on the cover?
"Moonlight Feels Right" by Starbuck.
And the funny thing is, they were from Atlanta!
Also these songs that mention Baltimore in the lyrics:
Engine Engine #9--Roger Miller
The Lady Came from Baltimore--Johnny Cash
Chattanooga Choo Choo--Glenn Miller
Anything by Ray Stevens (except "Everything Is Beautiful," "Turn Your Radio On," "Misty" and "Mr. Businessman")
Anything by Weird Al Yankovic
Anything by Cledus T. Judd
In Charleston, WV, none of the stations are owned by Clear Channel, but in Huntington, most everything is. And apparently the nearest station that carries "John Boy & Billy" in the morning is one of those?
