Cambridge Folk Festival doesn't have many chart-toppers, but Jim Croce was at No.1 in the American singles chart with Bad Bad Leroy Brown when he called there in July 1973.

He and Maury Muehleisen were given an empty slot and the compere - Isla St Clair - allowed them to over-run. However, this was at the expense of the next performer, who happened to be Bob Davenport. He definitely wasn't happy to see the "bloody Yankee" taking his allotted time.

Two months later, Jim Croce and Maury Muehleisen died when their aeroplane crashed in Louisiana.
