I can only guess that this is the first song I heard that I still listen to. It's about as old as I am and my mom really likes it. She use to play a record of it that I think I still have somewhere. It's a song you can't escape, commercials, summer radio, cover bands, it's everywhere.
I like the original version fine but there is an amazing cover byDave Schulz. I wish I had a link to a youtube video for it, but alas the closest I can get is the link to his website. It's listed as Margaweirdaville. This cover brings more of a Mariachi sound to it. The slower pace and dramatic music really bring a lamentation to the song that you just don't get from the original, not to mention the almost wailing/moaning vocal half way in. A bit of flare is added here and there in the song with a bit that sounds a little like the cantina music from Star Wars. All in all it's a great cover and I highly recommend it.
