Per Marco Minnemann:

Tonight's concert in London had a few surprises. First of all it was the only show on this leg on which Theo Travis joined us on stage again, and as always he played amazing. And Bono (who bought a few tickets, but I hear also was seen in Monaco?!) and also David Gilmour (who's a very lovely guy, it was so cool to meet him) came to the show, so yeah, no pressure :-)). Thanks again for the great reactions. Next stop, Wolverhampton. Stage picture by the one and only Lasse Hoile.
