Was looking for this for years, since I lost the vinyl. I was impressed then, I am impressed now. The next step after Concerto from Group And Orchestra. Amazing. He didn't talked much about it though, I looked through all interviews I could find... God bless his soul, I adored the man.
I have some hand written notes personally from John Lord. An english friend of mine was his postman and asked him something about the us group the residents and John lord made some online inquiries and gave them to him.
I have the vinyl album and it made hard listening when I was young. It's only later I can appreciate this music.
It's strange, but in the 70's you could do this as it was new, but somewhere everything changed and now we have nothing but jealous contempt from people who are supposed to know better.
