Strange and fantastic stage show loses following (5)
I believe the answer is:
eerie
'strange' is the definition.
(eerie means odd or strange)
'fantastic stage show loses following' is the wordplay.
'fantastic stage show' becomes 'feerie' (type of fantastical French drama).
'loses' suggests deleting specific letters.
'following' becomes 'f' (used when citing page numbers etc).
'feerie' with 'f' removed is 'EERIE'.
'and' is the link.
(Other definitions for eerie that I've seen before include "Spooky, macabre" , "Bloodcurdling" , "Unnatural" , "Frighteningly odd" , "Weird, uncanny" .)
