To celebrate Gov. Mark Dayton's expected signing of the same-sex marriage bill, Mayor Chris Coleman and the city of St. Paul will be throwing an outdoor concert Tuesday evening at Ecolab Plaza downtown.

The governor will sign the bill during a ceremony that begins at 5 p.m. at the Capitol. The concert will follow a procession led by the Minnesota Freedom Band from the State Capitol to Ecolab Plaza, 375 N. Wabasha St.

The "Love is Law" concert will feature several Minnesota groups, including the Jack Brass Band, Zoo Animal, the Suburbs, P.O.S and the Twin Cities Gay Men's Chorus. It will continue until about 10:15 p.m.
