A.J. I heard from Bruce M. and he provided a link that solves the mystery of the intro music to Beaker Street that I've/we've been looking for! It's the MOOG version of "House of The Rising Sun" and can be found here:
When you get to the link's website, you can click on the "House of The Rising Sun" and hear the entire version! It, and the other selections, are downloadable as well.
Please give Bruce M. all the credit for finding this...all I'm doing is passing on the information!
