Secret drinker comes to earth in Morecambe? (8)

Ross

I believe the answer is:

'secret' is the definition.
(similar in meaning)

'drinker comes to earth in morecambe?' is the wordplay.
'drinker' becomes 'sot' (sot is a kind of drinker).
'comes to' is a charade indicator (letters next to each other).
'earth' becomes 'e'.
'in' is an insertion indicator.
'morecambe?' becomes 'eric' (I've seen this in other clues).
'sot'+'e'='sote'
'sote' put inside 'eric' is 'ESOTERIC'.

(Other definitions for esoteric that I've seen before include "Other-worldly", "Understood by only a few people", "Occult", "Intelligible only to the initiated", "Mysterious to all but a chosen few".)

I've seen this clue in The Guardian.
