I know of people who go away for weekends of nostalgia, usually at a holiday camp or hotel on the coast, being served rubbish beer and even worse food. You know the sort of thing: four or five middle-aged musicians doing their material with nothing later than 1985 (or whenever they had their heyday). Ugh.

By the same token, do bands such as the Police, Led Zep, the Stones and other headliners have to charge such exorbitant ticket prices, thus relying on the Grey pound and probably denying younger people the chance to see them. They can't be short of a few bob after all.
