When Van met Martin

Belfast-born blues legend Van Morrison will be sharing the stage this weekend with a host of rock stars - among them BB King, Eric Clapton and The Rolling Stones.

The one-off superstar jamming event is being filmed as part of a documentary to be screened on US TV.

And which director has managed to bring this jaw-dropping line-up together?

None other than Martin ‘Marty to his friends’ Scorsese.

Sounds fantastic, but if you want to avoid this clash of the titanic egos, you’d do best to stay away from London's Abbey Road Studios this Sunday.
