Unknown British (?) up tempo big band piece

[apmnut]

Anyone know what the upbeat jazzy music heard at the 3 minute mark in this "redrawn" and colorized version of a B&W 20s cartoon is? I really dig it, and I suspect it's from a British library Ascher distributed since most of these used KPM and the like.

[WSBG Returns Yet Again!]

The piece in this is a track named "His And Hers" by Bernie Fenton (Conroy - BMLP 048). Here's a video I just made on this very piece itself.

Thank you!
