The sense of place and uniformly superb performances make it worth seeing, and maybe ultimately singing along with.
I was so surprised to find this on You Tube. I hosted several segments of the "Focus on Britain" series in the 1980s. It was produced by the British Tourist Authority. I haven't seen this in more than 25 years.
...and then, a month later, this turned up! I'd never seen it. I take the reader on the route traced by my book The Perfect London Walk. With an introduction by Sir MIchael Caine, no less. When a reader found his and told me about it, it had less than 100 hits, perhaps because the title didn't tempt Google.
