Robby Krieger knows how to throw an all-star concert in style.

The former Doors guitarist warmed up for this year's Scott Medlock - Robby Krieger St. Jude Invitational golf classic, a benefit for the St. Jude Children's Research Hospital, by getting onstage with a gaggle of famous friends that included Sebastian Bach, Alex Lifeson and Tommy Thayer.

Thanks to fan-shot footage of the show, we know the set list included some fairly intriguing song choices, leading to the unexpected (and altogether awesome) spectacle of members and ex-members of Skid Row, Rush, Kiss and the Doors coming together to cover Rush's 'Working Man' (which you can watch in the video at the top of this post) and Chicago's 'Saturday in the Park' (which you can watch below).

And that's just a small portion of what went down at the concert -- as you can see in the collection of videos posted at Heavy Metal Hill, the lineup also included appearances from Alice Cooper, Lita Ford, former Chicago drummer Danny Seraphine and Hawkwind mainstay Dave Brock.

Like most of you, we imagine, we can't wait for the live album. In the meantime, you can learn more about Medlock and Krieger's efforts on behalf of St. Jude's at this link.
