I stumbled across this yesterday while looking for an old Queen video.
"Radio Ga Ga"
It turns out that the inmates in the Cebu Provincial Rehabilitation and Detention Center in the Philippines are dancing as a non-violent means of rehabilitation. The warden (Byron Garcia) took a maximum-security prison riddled with gang violence and corrupt guards and decided to fire most of the guards and institute 4-5 hours of dance practice each day.
The result: a prison where 70% of the population consists of rapists, murderers, and other violent offenders has been transformed. It hasn't been completely free of controversy, but the results are interesting to watch nonetheless.
CNN news story on the prisoners
"Jailhouse Rock," a short (but very cool) documentary on the prisoners.
"Gloria" (yes, that "Gloria")
"I Need a Hero"
"Soulja Boy/ You Can't Touch This"
"Canon in D" (rock version)
