The Stones have been going - allowing for three or four personnel changes (Stu was a member, but not according to Andrew Oldham, and the odd session musician popping his clogs) - for over fifty years now. Only two full-time members of the band have died on them, although Brian had effectively already left.
Their fan base averages about forty, although the eldest are my age and the youngest are still not properly out of their nappies. They themselves range from Ron at barely 70 and the eldest, Charlie, is almost an octogenarian. Their combined age is around 300+ but to listen to them you'd think they were still in their 20s. Their musical range covers Blues, Rock, Country Rock, Reggae and some Latin-American.
I defy anyone to pin them down.
Aside from that my tastes range from Bachmann Turner Overdrive to Dr Feelgood by way of Beach Boys, Pink Floyd, The Who and The Eagles ...amongst others. A good feel for the geetar, a good rhythm section, horns sometimes, and solid vocals (apologies to Pete Townsend's reedy vocals).
