Much like NYC's Pride parade last month, spectators were dazzled by flamboyant costumes and colorful characters as marchers danced, sang, and just had a good time along the parade route from Oxford Street to Trafalgar Square. And what's a parade without politics? Sarah Brown, wife of Prime Minister Gordon Brown, also joined in the festivities by marching with the parade's first group.
