'friends' pokies profits' is the definition.
'winnings' can be an answer for 'profits' (synonyms). I am not certain of the 'friends' pokies' bit.

'hotel interrupts mccartney' is the wordplay.
'hotel' becomes 'inn' (inn is a kind of hotel).
'interrupts' indicates putting letters inside.
'mccartney' becomes 'wings' (I am not sure about this - if you are sure you should believe this answer much more).
'inn' placed inside 'wings' is 'WINNINGS'.

'and' is the link.
