Rock singer’s dicky but not having temperature (5)

I believe the answer is:

bowie

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

'rock' is the definition.
Both the definition and answer are singular nouns.
Maybe there's a link between them I don't understand?

I can't explain the remainder of the clue.

Can you help me to learn more?

(Other definitions for bowie that I've seen before include "Art rocker David" , "David --, rock singer/songwriter" , "American frontiersman, killed at the Alamo, 1836" , "David --, singer" , "Rock-based chameleon" .)

I've seen this clue in The Times.
