How many times Prince played aftershows with the Revolution and what do you think of the Revolution as a jam band?

i know for this one aftershoe in 1984 and great Paris New morning 1986.

The Revolution sounded great in improvisation on Paris New Morning

as good as any other band that followed

If you mean aftershows with the meaning that it was truly after an official show, then I think there were only 2, on August 13 and 14, 1986 in London. One was at Busby's and the other was at Kensington Roof Garden. The New Morning show was actually an unannounced show on an off night, so it wasn't an aftershow.
