I'm an Amazon Prime member, so I can watch "Upstairs, Downstairs" (the original series from the 1970s) on Amazon Prime Video for free. I often enjoy one or two episodes on a Sunday, if I can manage it.
"The Two Ronnies" (Ronnie Barker and Ronnie Corbett) were also from the 1970s. Mr. remembers them better than I do, but we're both enjoying the DVDs. The show has a little of everything: sketch comedy, stand-up comedy, parodies, and musical sketches. A couple of the Pythons (Michael Palin and Terry Jones) used to write for the shows, and we knew one of their special-material writers. The box set we got includes four Christmas specials---I'm looking forward to seeing those especially!
Thanks for the current PG Tips commercials! I'll look at those when I get home from the office. I didn't know PG Tips had their own YouTube channel!
