Rock song then cover of Erasure for rock group (10)
I believe the answer is:
stonehenge
'for rock group' is the definition.
(I've seen this before)
'rock song then cover of erasure' is the wordplay.
'rock' indicates anagramming the letters (the solver must 'rock' the letters around).
'cover of' says to hollow out the word (remove centre letters) (only the letters which cover the word).
'erasure' with its middle removed is 'ee'.
'song'+'then'+'ee'='songthenee'
'songthenee' anagrammed gives 'STONEHENGE'.
(Other definitions for stonehenge that I've seen before include "Megalithic monument on Salisbury Plain" , "Salisbury Plain circle" , "Wiltshire attraction" , "Wiltshire prehistoric monument" , "Druid comes here" .)
