Young rock-and-roller? (6)
I believe the answer is:
cradle
'young rock' is the definition.
'cradle' can be an answer for 'rock' (thesaurus). I am unsure of the 'young' bit.
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for cradle that I've seen before include "Cot for a small baby" , "situation far from grave" , "'When the bough breaks, the . . . . . . will fall'" , "Hold tenderly" , "Small bed on rockers" .)
