Gi'e us ten guitars...

Not ten guitars exactly and, to be honest, I'm not sure where this flurry of guitar-related internet activity came from, but here we go.

It's Guitar Week in The Guardian / Observer. If you didn't get the two-part guide in the weekend's papers they are online in their entirety (I think). With an added video ingredient. Very useful stuff even to these gnarled and rheumatic fingers. Every day this week (from Monday 12) they're publishing "songbooks" - tab, notation, chords - from, well, the usual suspects. You'll have to buy the paper for those though.
