This Way To The Rock Festival

The signs ('solar', you'll notice, this being Glastonbury) are out, ready for the invasion on Wednesday when traffic will be at its heaviest. As you'll also see, there was an alternative "rock" festival taking place at the Bath & West.

It was highly tempting to add a bit of band-related graffiti to the signs bottom left: Alt-J Route? AC/DC? or should it read Run DMC: Walk This Way? Possibly an I between the P and L on the one to the right?

Any suggestions for an appropriate caption by adding letters to the big sign?

Have it large!
