Comprehensive information on Morecambe, perhaps (7)
I believe the answer is:
'comprehensive' is the definition.
(I've seen this in another clue)
'information on morecambe perhaps' is the wordplay.
'information' becomes 'gen' (gen can informally mean information).
'on' means one lot of letters go next to another.
'morecambe perhaps' becomes 'eric' (Eric Morecambe).
(Other definitions for generic that I've seen before include "Collective" , "Applicable to an entire class or group" , "Not specific; of a class" , "in relation to class" , "cheap drug" .)
