These guys are thought to have the oldest musicians in the world. The Zimmers, out of England, have members as old as a 101. The name comes from the name for the walkers that old people typically use.
This is a paticularly ironic song - My Generation, sung by 'old people':
People try to put us d-down (Talkin' 'bout my generation)
Just because we get around (Talkin' 'bout my generation)
Things they do look awful c-c-cold (Talkin' 'bout my generation)
I hope I die before I get old (Talkin' 'bout my generation)
It's a bit of an ironic protest - part of the reason behind this song is the sort of imprisonment that the elderly feel in nursing homes and how they might essentially get abandoned by their families.
