Single on du Monde, vocals by Sharon Sims, by Sydney band formed in 1968 that went through several personnel changes and genres, from hard rock to psychedelia to Top 40 pop.
For recent news on Flake's flautist and saxophonist Dave Allen see his blog Burning Mountain Studio, which links to his pages on Flake history.
Suggestion from Mike Robbins, who also posted the video at YouTube and comments: Marmalade may have had the original UK hit, but with the fabulous vocals of Sharon Sims out front, this version by Flake wins hands down for me.
Further research? Six of their tracks, on four singles, were written or co-written by Russell Mabery who could be connected with 70s soul group The Mayberry Movement, one of whose members was Jesse Mabery. (See 2009 post by ady croasdell at soul-source.co.uk.)
Dean Ford (b.Thomas McAleese) wrote this song with band member Junior [William] Campbell. At YouTube, Dean Ford performs Reflections Of My Life in 2014, with content from 1969. The comments there and elsewhere show that the song has special meaning for some veterans who associate it with their Vietnam War days.

Marmalade had eight Top 10 hits in Britain including one #1, their cover version of The Beatles' Ob-La-Di, Ob-La-Da.

Eder: [Ob-La-Di, Ob-La-Da] become a number one hit in England and sold millions of copies around the world, generating a massive amount of radio exposure. The problem was that it wasn't really what the group was about. Marmalade was much more influenced by American soul, folk-rock, and progressive rock, but they had become locked into an image as a soft, bubblegum-type pop/rock band.
