BusterAg got me thinking - see his thread about thinking "Don't Worry. Be Happy" was a Bob Marley song.
What songs did you think were someone else for the longest time????
I made fun of him for that one but I do have a confession myself.
For the longest time - until maybe 7-8 years ago - I thought that "Stuck in the Middle With You" was song by George Harrison.
I had never even heard of the band Stealers Wheel but I was familiar with Gerry Rafferty (his big solo stuff like Baker Street of course which sounds significantly different). Anytime Stuck in the Middle With You came on my mind just processed it as George Harrison. It wasn't until the more recent days of car radios displaying the artists name that I caught it and was like "WTH???"
Anyway listen to "Got My Mind Set On You" by George Harrison and you might see why I confused it. Similar sound. Similar voice. Or even "All Those Years Ago".
Anyone else got some embarrassing examples?
