If you could choose a world tour by a band?

If you could choose a world tour by a band from any time in the past 50 years, that you would like to have toured with, which band and which tour would you choose? My own personal favourites would have been the "Joe Cocker Mad Dogs and Englishmen" tour of 1972 or perhaps the "Rolling Stones 1973 winter tour."

I guess though, any world tour with a major band or performer would be a lifes highlight.
