40a More optimistic, but to be executed : shoot!
Think it's osier - (R) osier but why "executed ..shoot"?
52a In gospel-singing era, less pop (6,3) L?N?E? / AGE
Any help please?
It's hardly the setter assuming that R = OR = BUT, is it?
Then R being executed (got rid of) gived (R)OSIER as Sammy says. If so, I don't believe it to be good setting. Perhaps someone will come up with a more sensible explanation.
