It was the 2005 concert at Wintershall that Roger appeared at, with Eric Clapton, Ringo, Mike Rutherford and many others.
Roger sang Say it's not true, Day of our Lives and I want to break free if I recall.
He also drummed on the final song I can't dance.
It bieng shown on Sky Arts late at night at the momnet so keep an eye out, it's been on a couple of times now so I am sure it will be on again.
