We know plenty about the movies of Stan Laurel and Oliver Hardy but very little about their wildly-successful tours of Europe. Crowds turned out in Elvis/Beatles numbers and the performances they gave were packed.
Some of this is covered very well in a half-hour radio special on BBC4 by film historian Glenn Mitchell, who managed to find many "lost" recordings of Stan and Ollie. You can hear it for the next few days at this link. Don't delay.
