Singer to get some ladies in a trance (7)
I believe the answer is:
sinatra
'singer' is the definition.
(Frank Sinatra)
'some ladies in a trance' is the wordplay.
'some' indicates the answer is hidden within the clue (some of the parts of the word are used).
'SINATRA' can be found hidden inside 'ladies in a trance'.
'to get' is the link.
(Other definitions for sinatra that I've seen before include "Artisan (anag) -- My Way singer" , "Entertainer" , "Vocal artist" , "'Ol' Blue Eyes'" , "Old singer" .)
