This must be the most popular karaoke song of all time; when I tried to find the "original" release, I found over 200 listings, many instrumentals by myriads of different groups.  I really got the wrong version of this song; I would have rather had the original that he sang on a 45.  This isn't it; it is a LIVE version; it's not bad, but see if you can find the original if you know the song well.  If you never heard the original, this version is fine, but for most of us, we can distinguish the slight differences.  My problem was I was not paying close enough attention; you only get 30 seconds to make up your mind, and this version sounded pretty good for the first 30 seconds.
