This past April, Noel Gallagher of Oasis was quoted as saying that Jay-Z should not headline the UK's Glastonbury Festival because he does not uphold the festival's guitar music based tradition.  Ouch.

To shove Gallagher's words back in his own face, Jay-Z started off his Glastonbury performance by walking out on stage strapped with a guitar and led the crowd in a sing-along of Oasis' "Wonderwall."  While Jay should probably stick to rapping over singing, I think Gallagher got the point and will stick to feuding with his band mates from now on.
