Thanks guys, really appreciate your comments.
Going off on a bit of a tangent here and being a huge Floyd fan...as I am sure there are many here, but who knew this?
My title was obviously borrowed from Pink Floyd. What I didn't know was Wikipediae - "According to an interview with Gilmour in the 2006 documentary Which One's Pink?, the studio version of the song contained minor guitar work both from Gilmour and Barrett, making "Set the Controls for the Heart of the Sun" the only Pink Floyd song that features all five band members, though some listeners may not fully discern the guitar tracks as they largely blend in with Richard Wright's keyboards and organs."
And this " Since this is about the path of a relationship from start to end, dawn to dusk as it were, it’s a journey" even more appropriate, but on the darker side it's probably about Syd Barrett...
Written in 1967 the year my Dad made the decision to move to OZ (we left in 1968) the track still sounds amazing.
