When you're the biggest rock'n'roll band in the world it's not surprising that even your special guests could headline festivals in their own right. Rumours are buzzing about who the band might invite to play with them when they perform at Glastonbury for the first time ever this Saturday, but a quick glance down the list of names that have already played with them on this tour leaves you none the wiser as to what direction they'll head in. They've had rock heroes like Dave Grohl and Pearl Jam's Eddie Vedder, old bluesmen like Taj Mahal, pure pop stars including Katy Perry and Taylor Swift and even cult icon Tom Waits. We've rounded up some of the best video highlights below, but the only thing that we can say for certain is that whoever turns up it'll be spectacular. Don't pin your hopes on any guest in particular. As a wise man once said, you can't always get what you want...
Dave Grohl - 'Bitch'
Eddie Vedder - 'Wild Horses'
Katy Perry - 'Beast Of Burden'
Taylor Swift - 'As Tears Go By'
