It's def. a touch of Flash n the Pan - the Easybeats writing team - and more.
It could also have gone towards Jimmy Nail's Ain't No Doubt.
The solo has a touch of The Chances of Anything Coming From Mars as well.
There's is some sibilant stuff happening as a result of the vocal effects.
COOL stuff.
I'm from the predisco era so can find common ground with Marty - PLUS Harry was THE BEST...there's also the classic Oz song...
