I parsed 16a as a synonym of "the grapevine" - hence ref to distilled - or "gossip column". Ref to Corrie Street was one Brits would pick up easily, but I'm not so sure about them across the pond.
22a - I still can't quite parse it.
I have 'eat pi' in 'me' - but I can't figure it.
21a took me ages to figure out - caret around l - despite some years as a proof-reader.
I certainly didn't get anything like the enjoyment I would expect from a Saturday puzzle.
