The Syn / Denny Ward

I'm trying to find out the status of Denny Ward, who performed vocals on one of the tracks by The Syn on their "Original Syn" compilation of early material:

I can find no reference other than this (and the many places it's been syndicated (no pun intended) on the web.

Anyone with specific knowledge? If not in, then this entry will have to go in with one of the lineups as just Jackman. No record of whatever other players were in the band at the time either.

Ward isn't in any of the lineups given in "The Tapestry of Delights":

... will treat accordingly.
