Ahh the Kazoo, almost the perfect instrument because it can be played tunefully by anyone with no skill and no practice... it surprises me a little that it isn't used more often in pop and rock - but here are a few that did find kazoo-love:

E102 - BMX Bandits

Strange - Galaxie 500

Crosstown Traffic - Jimi Hendrix

Everybody's Talkin' - Luna

Everybody's Talkin' - Luna (live from the last show)
