Stones just roll on
At last the Rolling Stones have made history by performing at the Glastonbury Festival, and despite the advancing years, Mick Jagger and his colleagues show no lessening of their passion and musical talents.
Some people might ask why it took so long to get the Rolling Stones to head up such a prestigious festival, but they demonstrated in great style that their appearance was "better late than never".
The Rolling Stones are showing to a sometimes ageist world that true talent can outlast the years, and they are also encouraging older people to keep on doing, and enjoying, what they do best. That is one way of achieving "satisfaction".
