Baffled

[olegrahl]

Years since I have been as comprehensively floored by a Gdn Saturday prize as by this one. Got most of the bottom half though can't parse 22ac (? know all) or 23d (?owns up). If anyone could help with Recording of Logical song (10) ---------K or One takes in American show (4) or One agrees Americans's behind record (8) maybe I won't have to cry myself to sleep.....
Got 15ac Soupcon but don't think it works. The çon is not pronounced con.
ScorpioJo, Lie-in King help me.

Letter patterns would help

22a Know-all - 'kno(b) + wall(y)' (stupid people, both contracted)
23d Owns up - 'own' + 's(tatement)' (primarily) + 'up' (in court)
9a,13d Soundtrack
1d US-ER
4d Assenter - 'ass' (American "behind") + 'enter' (record)

15a Yes - 'So up' (well excited) + 'con' (do; trick)
