Bono as Willy Wonka

I was just reading the July 8 issue of Hot Press and came across the
following quote from Ash about their time touring with U2.

"You can't help but be inspired when you tour with a band of that nature,"
say Huey Morgan. "We look at everything like Willy Wonka and the Chocolate
Factory. On the first album we were Charlie and Willy Wonka was played by
Bono. He showed us around the candy store."

I know Ash played with U2 at the Belfast Peace concert, but what other dates
did they tour together on the Popmart?
