Inmates at Cebu Provincial Detention and Rehabilitation Center (CPDRC), a maximum security prison in the Phillipines, have produced a tribute video to Michael Jackson that’s been viewed on YouTube more than three million times in the last five days.

The prison has a program that aims to rehabilitate through teaching choreographed dance. (A very unusual and holistic approach.) The CPDRC inmates did a version of the Thriller video and regularly perform pop music. Though this the clip is a little strange in some ways (because they’re prisoners, because Michael may have done things to almost land him in prison), but it’s also touching. There’s focus and dignity and grace–not to mention the coordination of 1,500 prisoners–that’s all very inspiring.
