Your kids like The Beatles. Your kids have a rocking sense of humor, especially acute when things turn silly. So it stands to reason your kids will dig The Rutles. Freaking Neil Innes and Eric Idle are Ron Nasty and Dirk McQuickly. This all started in '75 on Idle's British TV show but culminated in '78 when they were on SNL and then released the mocumentary, "All You Need is Cash." I should probably dig out some Bonzo Dog Doo Dah Band too... maybe tomorrow.
The Rutles, "Piggy in the Middle"
The Rutles, "Cheese and Onions"
The Rutles, "Goose-Step Mama"
The Rutles, "Ouch!"
A few good fan sites detail the whole shebang.
Try this one, or this one. Buy the CD. And the DVD.
OH and now anyone can post comments (I didn't realize I had it turned on members-only. That's so 80s of me.) Thanks Guy!
