RIP Peter Sallis. Thanks for all the fun.
We've speculated before that Sallis was very old (for those that only know him as Wallace he had a lead role in the UK's longest running sitcom 'Last of the Summer Wine' that ran from 1973 to 2010 and he was playing a retiree when that started) and whether the character would finish with him or whether they would carry on.
I hadn't realised that in some shorts and ads they had already used another actor, Ben Whitehead, for some short bits. He sounds pretty much the same, I think one of those you'd only notice small differences if told in advance.
