Conversation so far:
What is Animals?
In 1976, they recorded their tenth album, Animals, in their newly finished 24-track studio.
Was it a success?
Released in January 1977, the album peaked on the UK chart at number two, and the US chart at number three.
Did they go on tour?
Pink Floyd performed much of the album's material during their "In the Flesh" tour.
Where did they go on that tour?
At the Montreal Olympic Stadium, a group of noisy and enthusiastic fans in the front row of the audience irritated Waters so much that he spat at one of them.

Question: Has there been any other instances of spitting at fans or that sort of thing?
Self-contained rewrite: Besides Waters of Pink Floyd spitting on a fan at the Montreal Olympic Stadium, has there been any other instances of spitting at fans or that sort of thing?
