When I used to play now and then with a comedy band that included the late Milky Keith on tea chest bass, I used to ask him for an A as I tuned up the guitar or banjo. Despite the laugh this got, it wasn't that far from reality........
Of course, over your side of the pond, wash tubs are more popular. Something to do with throwing all the tea chests into Boston Harbour so not having any for musical purposes.......
