Band that plays Under the Sea/Tiki Room, MK entrance loop

[Davey Duck]

Anyone know the name of the band that plays "Under the Sea" and "Tiki Room" in the entrance loop at MK? Sounds like a big band or orchestra.

I'm not certain, as the entire loop is all instrumental versions of songs. I don't think they were known bands so much as Disney's in-house musicians creating the tracks.
