Almost, it sounds a jazz rock song written by Frank Zappa (and probably by the talented mulsti-instrumentalist Ian Underwood, but that’s another story), because it is actually based on Zappa’s „Little umbrellas“ which appear on his infamous jazz rock album „Hot Rats“. Although, the details on the discogs website about WSC read „Music by dEUS, Sample by „Little umbrellas“, I would put it this way: dEUS basically added the lyrics to a cover of this instrumental and renamed it. I think that this is an import detail here.
