Morecambe & Wise Legionnaires Sketch

I caught the end of the Ernie Wise programme in the week, there was a few snippets of M&W sketches at the end, one bit was the two of them washing their hands in a public toilet dressed as French legionnaires with the Kepi on & the neck covering. Ernie washed his hands & turned to use an old roller towel dispenser. Eric turned & pulled a length of towel from Ernie's Kepi. You could see it coming a mile off, but this 10-20 second clip was the funniest thing I've seen all week. It was simple, perfectly performed & funny.

I've been looking for a copy of that clip on YouTube or similar since, can't find it anywhere. Do you know it? Can you point me to it?
