Not sure if that's his real mother, but that is without doubt Brixton, where Danny was born and lived at that time (1968). Right at the very end of the clip, the building Danny is walking towards is The Queen, a pub which was demolished about five years ago.

Brixton Academy (music venue) is very close by, and the street which Danny appeared to live on is Bellefields Road. Apartments in that street now fetch, on average, £330,000.
