Not for a very long time and I don’t think I would have bothered with the credits in my youth; but your hint and google have enlightened me. Thanks: itch scratched!
Thanks Jono. It just grated a little. Your suggestion is an improvement on Azed's. Other than perhaps "providing some inspiration for", which I'd still not be happy with, I'm struggling to find ways to make the surface work.
I thought 2d was OK. "Inspire" can be a container or insertion indicator; here it means insertion. So we have the def, that which is inserted into the fodder. (First def of "what" is "that which").
Thanks buddy. I'd still have difficulty in equating "that which inspires [fodder]" to "that which is inspired in [fodder]", but good to know that others seem to think it's OK!
