Alan there are multiple definitions of street photography. Also there are many genres closely related to "street" photography, probably way to many.
I think Eric Kim in his book gets it right.

"To start off, street photography is whatever you make of it.
There are no “right” and “wrong” definitions in street photography.
Street photography is simply the art of wandering in public places, and taking photos of whatever interests you.
You don’t need to adhere yourself to any “rules.” Street photography is the most democratic form of photography— because all you need is a public place, and a camera, to document whatever you find interesting, and personally-meaningful to you.
If I could define street photography, it would simply be: “Documenting humanity.” “Humanity” can be defined however you want."
Of course closely related to "street" is social commentary, e.g., "White Angle Breadline" and "Migrant Mother" by Dorothea Lange. There is the classic photo essay fathered by W. Eugene Smith, "Country Doctor," "Nurse Midwife," Spanish Village," "Alberta Schweitzer," "Dream Street" and of course "Minamata." Street is closely rated to photojournalism - in the telling of a story. Then there is the classic shots of Henri Cartier Bresson, Gary Winogrand, Robert Capa.
Then there was one of the greatest "street" photographs of all time, "V-J Day in Times Square" a.k.a., "The Kiss" by Alfred Eisenstaedt. It has stirred controversy over the years. Multiple 25 foot statues of this incident has been made, with one standing in on Sarasota bay in Sarasota, FL, one in downtown San Diego, CA. and one in Times Square.
Gene Smith was always bothered with the hard lines many wanted to put to pigeonhole the broad area of street photography into photojournalism, social documentary, documentary, etc., with his infamous quote, "Hardening of the categories causes art disease." I prefer Eric Kim's approach.
So yes - your image is a classic "street shot." What is more street than street performers, be they in Key West, the San Francisco wharf or London.
