They're always having fun at airports and on planes. The controversy rages on about what the "J33-3" on the airport sign means, that's featured on the cover of ATYCLB (but I'll leave that debate off FT). I've seen countless photos over the years of them fooling around with baggage carts and the like. And there's a bootleg of a few songs Bono recorded on a plane once (R&H tour?).
And speaking of the R&H tour,
motnot, being in Tempe, any chance you were at Sun Devil Stadium for the R&H video shoot?
