Yes Holiday on the Buses was filmed on location in North Wales but the other scenes were shot at Elstree Studios in Borehamwood where that bus terminus canteen scene will have been made. , Herts Not far from Stevenage possibly. Or Haringay for that matter.
Plot thickens then. Although Haringey Borough were actually formed in 1970. That said can’t belive a team that new would be attracting headlines like that.But Stevenage weren't formed until 1976, and Holiday on the Buses (an absolute classic BTW) came out in 1973, so unlikely to be Stevenage. Harringay were not formed until 1973, so again unlikely to be them either.
