NFL's DeMarcus Ware Sings 'Purple Rain' with High School Band

Here's Denver Broncos superstar DeMarcus Ware performing Prince's "Purple Rain" with his old high school band ... and it's pretty damn good.

Ware reconnected with Mirage -- an R&B group he joined as a teenager -- for a special performance at the "A Taste of the Broncos" charity fundraising event at Mile High Stadium in Denver.

The event raised close to $100k for Food Bank of the Rockies -- which helps feed the needy.

Good event. Great music.
