Singing-on -the -Street

I have heard this man singing on St Georges bridge several times. It's not the warmest spot, an icy wind whistles over it from the river. But he tells me folk hear him better here. I sat and listened eating ice cream ( yes really ) and enjoyed his version of 'Crazy Man Micheal'.

I'm feeling dull on Blip folks.
I do appreciate those of you who respond to me : your kindness is valued.
I'm not sure I have an answer.
