I saw them 4/9 and 4/10 and both nights, once the show was over and the houselights came on, a U2 song was played. Could someone please tell me the name of this song? I have posed this question on several 'U2' sites - to no avail. Also, the song I'm thinking of is NOT Julee Cruise's 'It's The End Of The World As We Know It' which some people have suggested.

Thank you!
