Song were copyrighted when they were recorded, hence the ABKCO Music tracks on all of Sticky and the 5 on Exile. Had they never been released, they were still copyrighted to ABKCO. So there's certainly other unreleased tracks from the 1960s through the Fingers sessions that are unreleased ABKCO Music copyrighted songs.
"Youve just made my day" is out there; it's medley. Not a medly; a mess od edits spliced together. And "English Summer"; wasn't that another working title fro SFM? I know I have "English Summer" on a boot vinyl 45 somewhere.
Pretty sure "English Summer" is the proper working title for what is labelled on boots as "Sometimes Happy, Sometimes Blue" - Keith's vowel movements for what finally became "Dandelion." If I recall correctly, Marianne Faithfull was supposed to cover "English Summer" as well (this would have been late 1966) so I think "Dandelion" is a more likely bet than "Street Fighting Man." The working title for "Street Fighting Man" as a backing track was "Primo Grande." The first attempt at the song with lyrics is "Pay Your Dues."
