Swing and lounge had a bit of a resurgence in the '90s. It was probably a 'blink and you'll miss it' fad, but it was a whole thing for a certain demographic.
I say this as a genuinely uncool person who had listened to very old music from a very young age. (see username) It was unnerving to have other young people suddenly expressing positive interest in my record collection, but it was also nice that companies were reissuing some better content on CD.
That being said, Vic Fontaine was cartoonish and I hated those episodes. If it was meant to be a homage, it was a poor one.
