What is street performances called?

yes there is a street called samabula street

yes, there is a elm street in New jersey,it is close to Atlantic city

Its called "street dance" because it originated on city streets in the late 1980's and early 1999's. It was a way for gangs to stop trying to kill each other. :)

Simply put, Because as a busier road it was of better construction and was a higher 'Class' than other tributary roads joining on to it from poorer housing areas...

Because the road was probably named to celebrate the coronation of Queen Victoria or a later monarch
