An Alternative Universe

I accidentally started watching 'Last of the Summer Wine' just now (please don't judge me). As the youth would say 'WTF?'. I suspect that i've been drugged, but it seems that the main protagonists of this programme (Compo Clegg and Foggy as memory serves), have been replaced by George off of George and Mildred, Kato off of the Pink Panther films and Russ Abbott.
