From the Songs you won't hear on the radio files:
I spent a lot of time trolling through cutout racks in the 70s. I discovered this gem in 1975. Took it a year to make it from LA to Fred, Texas. The album featured an incredible trombone-laden, barbershop quartet version of Purple Haze that revolutionized my life. They closed with this version of Happy Trails that Van Halen later ripped off.
Noted for obliterating classics like Swan Lake (Swamp Lake) and Hungarian Dance No. 5. Here's their redition of the Flight of the Bumble Bee aka Bumble Bee Boogie.
How about the Beer Bottle Polka?
