It may be a sad day for Foo Fighters fans. The Foo Fighters closed out the Reading Festival on Sunday and it may be the rockers' final concert for the foreseeable future. Foo frontman Dave Grohl made the sad announcement during their performance at the festival saying, "Well, well, well. The Reading festival. You guys realize we've got a lot of songs to play. It's the last show of the tour and it's the last show for a long time."
