Wow, I've never heard of more than two or three of those bands! And had no idea that "The Rutles" existed as an idea as early as '75. Can't wait to get home and give these a listen, they're all blocked here at work.
To be clear, Heables, am I right in assuming that none of these bands sounded Beatle-like for more than a song or two in their careers and that these tracks are all the exceptions?
