MST3K theme mp3

I’m looking for an mp3 of the MST3k theme so I can use it as a ringtone. Can I find this on sale or for free anywhere on the internet (assuming it’s legal, of course)? I would prefer the instrumental music that plays into commercial breaks, but I would take an mp3 of the entire theme as well.

I was hoping the MST3K movie had a soundtrack, but I can’t find it anywhere. Can the SDMB help?

search for mst3k

at least one theme is in there

Somewhere I have two CDs that were commercially released by the Best Brains people. They included several versions of the themes they used, as well as lots of their best musical bits. You might still find them on sale on the BB website, or on ebay.
