I love Queen's music, but I'm not a trivia buff; I'm liable to get the minutia wrong; still, I admire them for their huge musical knowledge, and diversity of writing/performing styles.
I have a good friend who adores Queen. I've sent her the edress of this BB, in case she has stuff to add.
I wonder if "Hoople" is the origin of that expression, "Hoopla", meaning a lot of commotion and chaos...
