Tom takes in show: this one? (7)

I believe the answer is:

cabaret

I'm a little stuck... Click here to teach me more about this clue!

'show this one?' is the definition.
'cabaret' can be an answer for 'show' (I've seen this before). I'm unsure of the 'this one?' bit.

I don't understand the rest of the clue.

Can you help me to learn more?

(Other definitions for cabaret that I've seen before include "Variety entertainment" , "Entertainment provided in a nightclub" , "Liza Minnelli's entertainment?" , "Film set in 1931 Berlin - floor show" , "Series of acts" .)

I've seen this clue in The Sun.
