Queen Elizabeth II's
subjects serenaded her with impromptu renditions of "Happy Birthday,"
on Sunday, as the monarch slowly drove past some 10,000 people attending
a massive street fair in her honor.
The drive past in the "Queen mobile" was the highlight of the party on The Mall, the road leading to Buckingham Palace. The picnic is the grand finale of a weekend of official events marking the monarch's 90th birthday and celebrated some 600 charities to which she lends her patronage.
