The excellent british comic, Arthur Smith, apparently once quipped:
North London has blue plaques saying who lived where, south London has yellow signs saying who was mugged where.
My favourite blue plaques are these:

On the left is the house Jimi Hendrix lived in. On the right, the house George Frideric Handel lived in.
Must be on some musical ley-line :-}
I wonder what Handel would have made of “Cross Town Traffic”.
