There's an entire blog dedicated to Jimi Hendrix's banter. It's called, not surprisingly, Jimi Banter.
My favorite Jimi banter is the one before "Machine Gun" on the "Band of Gypsys" album. It's both funny and touching - but after that 10-minute Stratocaster blitzkrieg, that banter sounds so meaningful.
It's sad that I am such a Jimi fanboy I find even his banter profound.
