Anyone remember...

"Oh what a pity the pubs in the City all close at half past ten!
If I had the power they'd shut for an hour then open up again...

OH! I could get chronic on vodka and tonic at any time I like -
I'd wave at the p'liceman standing by my car, then nick his bike!

And we'd all have a damn good time!
(Barker) On peaches and cream!
(Corbett) And vodka and lime!"

Can anyone please please tell me which episode I can find this song in?? I seem to remember they were arguing about whether to go for something to eat or something to drink!

Many many thanks in advance!
