Hi, First time posting..

I'm just wondering if anyone knows if there is a BIAB style for this kind of music that I adore!

It's a sort of lively 2-step orchestral style (I bet there's a name for it, but I don't know what it is!) that's heard a lot in show-tunes and stuff from 'the golden age of light music' 1940s - 1950s

I'm linking two examples of the style here. The first, "Star Parade" (https://www.youtube.com/watch?v=mSbEdvGyW1A) sounds like a TV studio Big Band, the second, "Happy-Go-Lively" (https://www.youtube.com/watch?v=xOZu3NiBjBk) sounds more like a 1940's light music radio orchestra..

Any help would be most appreciated - even if you just know what the style is called, that would be a start!!

Many thanks, Steve xx
