15a More than one clever chap scratching head for hours, and 17d Would-be setter, not about to join rave. I think the answers are Ages, and Aspirant, but can't parse them. Help would be appreciated.
Thanks, Jono. I was pretty chuffed when I saw Aspic, setter, today - I hadn't yesterday when I did the puzzle! I often just shove in the correct answers because they're correct - it's not a totally good system.
