A bishop is performing at back of hotel as member of a group (8)
I believe the answer is:
harrison
'member of a group' is the definition.
(George Harrison of The Beatles)
'a bishop is performing at back of hotel as' is the wordplay.
'a bishop' becomes 'rr' (abbreviation for Right Reverend).
'performing' becomes 'on' (as in being on stage).
'at back of' says to put letters next to each other.
'hotel as' becomes 'ha' (this might be a standard abbreviation I've not previously seen).
'rr'+'is'+'on'='rrison'
'rrison' put after 'ha' is 'HARRISON'.
Can you help me to learn more?
(Other definitions for harrison that I've seen before include "George maybe" , "-- Birtwistle, composer" , "'... Ford, film star (8)'" , "Member of group" , "Guitarist, George - actor, Rex" .)
