The magic occurred on Monday night at a charity concert 'Cancer For College' in Seattle. They were joined by Dave Matthews Band's Stefan Lessard and folk artist Brandi Carlie. They went under the name 'One Classy Night' to raise money for cancer survivors in need of scholarships. The event raised $300,000 for the charity.

Ferrell conducted a drawn-out mic check before bringing on 'local, homegrown kid' Eddie Vedder and the rest of the band. Check it out below:
