I can understand Shelley's adverse reaction to being spat on even if it was a sign of appreciation.
He was something of a diva in other ways as was revealed in a Radio 4 documentary about contract 'riders' - little or not so little extras bands insist on before they perform.
The Buzzcocks, if I recall, had to have a crate of Moet et Chandon Non-Vintage in their dressing room.
One promoter couldn't get it, so substituted more expensive vintage champagne.
The band rejected it.
As the manager said at the time: "No Moet, no show-ay, no Chandon, no band on."
Which goes to show they were just as far up their own backsides as the old dinosaur rock bands they were seeking to replace.
