I don’t want to make myself a pariah by not giving you the solution, so here it comes. The completed grid is behind this link. The clue explainers are in the following video, and a bit about the theme to follow.

You’ll find DANIELLE DAX hiding in the grid, a POP MUSIC SONGSTER, once of the LEMON[ades] KITTENS, whose songs include CATHOUSE and WHITE KNUCKLE RIDE. Allusions in the first post were to her songs Flashback and Funtime, and her retrospective lp titled “Comatose Non-Reaction (The Thwarted Pop Career of Danielle Dax)”.
