Roger Glover's first solo album post DP-resignation: The Butterfly Ball & the Grasshopper's Feast (a children's illustrated book that was supposed to be turned into an animated movie, it was basically a soundtrack work).
He delved back deeply into his Beatles background for the music.
The financing went awry and a live concert was staged (with Vincent Price as the narrator) with lots of Purplelites (even from the then new Burn line-up, Roger was graceful enough) and assorted Brit rock stars. But that didn't garner the necessary financial interest for the project either though the concert was well-visited (it was also Ian Gillan's return to the stage after his departure from DP, he deputized for Ronnie Dio who had sung on the album, but Blackmore - by then his boss in Rainbow - didn't allow him to do the concert with Roger).
The studio album is still readily available in remastered form, but the live gig (which was recorded and turned into a concert movie at the time) has all kinds of publishing rights hassles affiliated to it, a VHS that came out ages ago was quickly injuncted from the market. Since then Roger has talked again and again about remixing it properly and bringing it out again, but I think he has given up by now, it's just too difficult. I'm surprised the stuff is on Youtube, I've never seen it before myself and I'm the resident Purp Nerd!
The project even spawned two reasonable single hits, the Dio-sung Beatles spoof "Love is All (you need)" ( a pun on All You Need is Love), note how the cheap animation in it has nothing to do with the intricate drawings in the book
and the John Lawton sung Little Chalk Blue (a blueprint for many Uriah Heep ballads he would sing when he joined that band in part on the strength of that particular gig which gave him visibility in the UK, he lived in Germany at the time)
The album is full of little gems of people singing out of their mold, here is the boy from Redcar long before he became entangled with C movie American actrices who would crawl on Jaguar hoods...
