The Temperance Seven, "Pasadena"
The "trad jazz" movement in the U.K. started in the post-war period, hearkened back to earlier sounds, those of '20s and '30s dance bands and Dixieland jazz. It flourished in a period of want, dislocation, and disillusionment as the nation recovered from the war and, perhaps, sought comfort in the music of the entre-deux-guerres.
The Temperance Seven were a lighter-hearted, or, perhaps, more tongue-in-cheek, version of the typical sound and ensemble.
Further along the tongue-in-cheek spectrum:
Bonzo Dog Doo Dah Band, "Won't You Come Home, Bill Bailey?"
The Bonzos (né Bonzo Dog Dada Band), on the other hand, were musical absurdists who took the trad jazz sound and used it as a launching pad for their own fancies. Their sound would grow to absorb (and parody) more-contemporary sounds of the mid- and late '60s. But here, on children's TV show Blue Peter, it's very much trad jazz meets Spike Jones.
Oh, who's Spike Jones…?
And here's namesake Bonzo, as drawn by creator George Studdy in 1935:
