This may be a semi-good thread for this request, economizing without starting another one and taking advantage of all the music gurus in one place.

I don't have access to my clip/soundtrack libraries at the moment. Sorry, but this is TOS, not TAS.
Does anyone know the name of the percussive piano (and, as the cue progresses, horns) cue that is used at the following junctures? It's the music that plays (in long form) near the end of "Catspaw" when Kirk and Spock emerge from the cell through the ceiling hole and battle the Sylvia-controlled McCoy, Scotty, and Sulu. It's later used, in abbreviated form, in "Mirror, Mirror" when Kirk and Mirror Sulu have their short little face-off in Sickbay after Marlena eliminates the guards with the Tantalus Field, and is also heard in "The Changeling" (also in abbreviated form) when Kirk and Spock are alerted that Nomad has broken into Sickbay. It begins with a six-note motif played low on a piano, twice (I have bargain-basement "perfect" pitch and can supply the notes of the motif if needed), and in abbreviated form, that's pretty much the extent of the cue, but when it goes longer (as in "Catspaw"), a bunch of horns come in. It's a very vivace (or con brio) piece that moves quickly and is clearly meant to convey action. Great stuff. I thought it came from S1 (specifically "Shore Leave") but haven't been able to find it there, and in recently rewatching "Catspaw" I was surprised to find it there in extended form.
