O-Din REALLY needs to go on vacation methinks...
I'll play though Spicoli since this is kinda my trickeration!
The title of the thread is kinda narrow-ish in scope since most of the bands listed on the previous page were well established/playing bEfOrE the 40's but, it's copacetic; I get what you're trying to lay down.
Too many good bands to choose from!
I think it would be a cool idea to make multiple machines based on the most popular spots of the swing era and each machine would have a theme reflecting the decor as well as the bands that played there.
Savoy Ballroom's machine could have a Chick Webb Gretsch-Gladstone drum set bash toy, bandstand ball lock, lindy hopper centrifuge, "cutting contest" riffin' ramps/diverters, Ella Fitzgerald spinners (that scat when hit), bouncer bumpers, etc...etc...
I could go on and on about each machine's layout/music selection but you'd probably put me on perma-ignore faster than you could say "F@&!'N SCREEN DOOR!"
I guess if you're asking though O-Din,
This would be a strong contender in my house-o-roonie.
