I think there's a mistake ....if the 15 Across clue of Actor McGregor answer of EWAN is right then the 16 Down clue of Lug (3) should give the answer as Ear but the ""A" of Ewan gives the answer of A?r....something not right.
I like the Afirkans lug = air,
Being this is a scots based crossword,
Thinking that a mistake has been made,
As Said Ewan is spelt with an E, and lug is ear.
Any more comments ?
