I'm wondering if no. 4. is Carollers.
Using the answer caro-sell+one letter as a "sound alike". Can't explain why it would be roundabouts (plural). Any thoughts mallyh?
sorry bobb, we've cross posted, I meant the answer under yours, where the answer might be carousel plus one more letter, but done as a "sound alike" anagram i.e. caro-sell (plus letter "R") to make carollers. ???
