U2 hint at headlining Glastonbury 2011
U2 have hinted that they will headline Glastonbury 2011, telling fans to ``watch this space''.
The appearance by the veteran British rock group follows weeks of rumours that the Stones, who in 2012 celebrated 50 years in the music business with a handful of concerts, finally would play at Glastonbury, one of Europe's biggest music festivals.
