The top (bottom?) 100 worst covers of all time. Should you be a masochist, there are plenty of video clips and sound files on Retrocrush. Here are some of the most hideous.
You shook me all night long by Celine Dion (and Anastacia who does much better).
My generation by Hilary Duff. (On top of everything else wrong with the execution, she misses the point with 'Hope I don't die before I get old'.)
Do ya think I'm sexy? by Tiny Tim
In a metal mood by Pat Boone, an album that includes such winners as No more Mr Nice Guy, It's a long way to the top (if you want to rock and roll), Smoke on the water and The wind cries Mary. You really have to listen to these sound files.
Rocket Man by William Shatner.
Don't say I didn't warn you.
