Actually, there were two, "Bridge Over Troubled Water" and Bill's holdover "Suffragette Song"
Billy Joel - Piano Man (1973)
And for some laughs (NSFW):
One With Joel and Down On Your Knees, I'm the Piano God from [I]Robot Chicken[/I] (with Zac Efron as Billy Joel)
"It's late September and I really should be back at School"....
Rod Stewart - Maggie May (1971)
More electronic classics:
Kraftwerk - Autobahn (1974)
I got a little confused, but if Suffragette City has been legally nominated, I'm officially seconding it.
Ok, how about another instrumental classic? This tune had been making the rounds in one form or another for a couple of decades, but made famous by Eric Weissberg's version for the movie Deliverance in 1972. Released as a single in 1973.
Eric Weissberg -- Dueling Banjos (1972)
Simon and Garfunkel - Cecilia (1970)
Nitty Gritty Dirt Band - Mr. Bojangles (1970)
Hearts are tough, she said, most times hearts don't break, and I'm sure that's right . . . but what about then? What about who we were then? What about hearts in Atlantis?
Black Sabbath - Paranoid (1970)
Gordon Lightfoot -- If You Could Read My Mind (1970)
Queen - Killer Queen (1974)
So, wow, there are 17 unseconded tracks as of now
I'd like to nominate
Bob Marley and The Wailers - Soul Rebel (1970)
Only the gentle are ever really strong.
Time to get funky!
MFSB - TSOP (The Sound of Philadelphia) (1973)
Fixed, try now?
