What started out as a 50th birthday celebration hang for Philly Live Nation head honcho Geoff Gordon ended up much bigger.

Last night the Grateful Dead’s Bob Weir was in town to play a show at the Tower Theater in Upper Darby, the place where Gordon was planing to have post-show gathering for his big 5-0. There was a party to celebrate, however something greater happened: Gordon surprised all in attendance and got married to his girlfriend – now wife – Sayeeda Gordon.

The wedding officiate? None other than Bob Weir himself.

According to Jim Sutcliffe of Live Nation, who was in attendance, when Weir heard the news, he married Geoff and Sayeeda in between sets. Our congrats to Geoff and Sayeeda.

Below, watch a fan video of “Not Fade Away” from the show last night.
