Attila Zoller April 1962
Fitzgerald's Attila Zoller discography (jazzdiscography.com) has no personnel variance, but another discography website (http://theboogiemanwillgetya.blogspot.com/2012/05/night-bounce-and-reque...) specifies that Diernhammer only plays on 3 tracks.
As far as location: fitzgerald is unsure (lists it as "Austria?"), but the boogieman discographer lists it as munich, germany. -JS
