A flashmob formed at rush hour yesterday in London taking the Rick Rolled web phenomenon to the streets.

You possibly already got "Rick Rolled" and have watched the pop star Rick Astley perform his hit from the 80s "I Never Gonna Give You Up". 10 million already viewed his video on Youtube.
The Rick Astley flashmob drew out about 400-500 people and of course they sang Never Gonna Give You Up before they broke up in all directions heading for the next pub.
More details on the BBC News.
