What a brilliant rendition of the song this is! Something seems to have happened to the sound on my recording but hopefully it doesn't detract too much from the brilliance of this busker!
I happened across this busker whilst taking the long way home. She had drawn quite a crowd close to Hungerford Bridge and her strident vocals caused me to pause. Here are the first two of the songs I heard. Unfortunately the first is marred by the engine of an ice cream van but I moved to a better position for the second. If anybody knows who the artist is please let me know so I can credit her.
