I've been working my way through a local quiz and have found myself unable to answer three of the questions. All the questions are linked to pearls in some way and are as follows:
1. Reminder of when barrow boys were more commonthan supermarkets. (6,5)
2. Most rare and costly pearls. (5,6)
3. Sounds like; insulation; not heavy. (7)
I was wondering if the first one could be linked to the Pearly Kings and Queens of the East End.
