“South American Getaway”: Sunshine Pop’s Case of the Blahs

This track sounds like a collaboration between Burt Bacharach and Brian Wilson – only it isn’t.  Although it wants to be:

Just like The 5th Dimension’s “Dimension 5ive,” this is technically a vocal tune yet one without lyrics.  It also has that sunny Southern California vibe – at first – but by song’s end, I would have to describe the overriding emotion as closer to melancholy.  Sunshine pop contemplating its navel … orange.

I found this Burt Bacharach composition on the soundtrack to the film, Butch Cassidy & the Sundance Kid – released 1969, roughly the same time period as “Dimension 5ive.”  These two songs together might comprise sunshine pop’s “progressive peak.”   But are there other songs that merit inclusion in such an elite group?
