One books male singer: to acquire female as stripper, finally? (2,3,10)
I believe the answer is:
in the altogether
'as stripper finally?' is the definition.
(in the altogether means naked)
'one books male singer to acquire female' is the wordplay.
'one books' becomes 'inthe' (I can't explain this - if you can you should believe this answer much more).
'male singer' becomes 'alto' (type of singing voice).
'to acquire' becomes 'get' ('get' can be a synonym of 'acquire').
'female' becomes 'her' (I've seen this before).
'inthe'+'alto'+'get'+'her'='IN THE ALTOGETHER'
(Other definitions for in the altogether that I've seen before include "wearing nothing?" , "exposed" , "Naked" , "barely seen" , "having nothing to wear?" .)
