Did rock celebrity ultimately meet all the crowd? (8)
I believe the answer is:
startled
'did rock' is the definition.
(ie rocked)
'celebrity ultimately meet all the crowd?' is the wordplay.
'celebrity' becomes 'star' (I've seen this before**).
'ultimately' says to take the final letters.
The final letters of 'meet all the crowd' are 'tled'.
'star'+'tled'='STARTLED'
(Other definitions for startled that I've seen before include "Taken aback" , "Taken by surprise" , "Frightened or surprised suddenly" , "Surprised with fright" , "Scared" .)
