Stuck on last three clues:
16 across - "animated liveliness" (8). I have ?i?a?i?k
48 across - "if really necessary" (2,1,4) I have a?,a,?u??
39 down - "very attractive person" (9) I have s?a?????o
Many thanks for "at a push". Easy now I see it!!
Animated liveliness could also be vitality as well as vivacity. This would mean that the answer to 8 down "smooth and polished" is not "slick" as I thought. The word then would be S?I?Y. Any ideas?
Don't know the word smasheroo and can't find it in the dictionary but it may be right.
Many thanks for your help.
