What would you call this keyboard sound?

At one of their series of weekend "conventions" Marillion did a cover of the Split Enz song Six Months on a Leaky Boat, and Mark Kelly uses this synth keyboard sound that I just love, but I don't know what you'd call it. For some reason Wurlitzer came to mind, but it has much more of a carousel music sort of sound. You can hear it here - go to 1:53, he plays a little cabaret kind of intro then goes into the sound I'm talking about for a few bars:

Calliope comes to mind.

Yeah, I guess that's why I said carousel - that's it. I enjoy it, in small doses. If there was a prog band that based its sound around it it'd probably drive me nuts!
