TMK,, we have only heard Echoes of Heroes from live La Cave recording, and a reworked and recorded versions of The Lost Children on Sunday Concert, and Too Much to Lose on Songbook (in an alternate key) … these demos have been in the public's hands for a few decades… i don't know why someone has chosen to recently make videos from the old audio recordings… it would be nice if something unheard surfaces, either posthumously, or humorously
