Grease-therapy

I know that light-therapy (mainly works for Scandinavians living 6 months in darkness), talk-therapy, energy-therapy, you-name-it-therapy, have been tried to help against depression. But has anyone tried Grease-therapy?

Put on "Summer nights", "Oh, Sandy", "You're the one that I want" or anyother of the everlasting hits, and I swear that the world will start dancing in good old fifties style, and feel good!
