On Sunday May 11th 1969  a young, up and coming band named Led Zeppelin played on a small lake just north of Seattle Washington. Thats right they played ON the lake. The venue was Seattle's Greenlake Auqa Theater, The 5,000 seat Aqua Theater on the southwest shores of Green Lake.

The Seattle Post-Intelligencer reported "several thousand of the whimsically clad and nearly unclad younger set" attended. 

The Setlist (posted on Led Zeppelin.com) included the songs  Train Kept a Rollin', I Can't Quit You Baby, Dazed and Confused, As Long As I Have You, Killing Floor, White Summer / Black Mountainside, Babe I'm Gonna Leave You, You Shook Me, How Many More Times and  Communication Breakdown.
