Flash mob a cappella
- According to The Independent the lasted fad in the rather humorous
practice of "Flash Mobs" is the recent incarnation of rick mobbing,
rick rolling or, to give it its full Latin name, The Rick Astley Flash
Mob, in which hundreds of people descend on a rush-hour station
concourse and sing, a cappella, the lyrics to "Never Gonna Give You
Up". And then leave.
