In all honesty, I don't know much more about Wallinger nor the bands with which he was associated, but The Waterboys' The Whole of the Moon remains one of my favorite pop/rock songs from the 1980s, mostly for the back-and-forth contrasts within the lyrics and the song's simple yet catchy carnivalesque foundation, upon which the band adds layers of instrumentation and backing vocals resulting in a culminating crescendo via a sax solo.
I must confess, any pop song that features violins, trumpets, and a saxophone automatically receives bonus points from me.
Anyway, Wallinger is the chap playing the keyboards in the video below.
