WASHINGTON (AP) A backup chorus that included Nancy Pelosi, Kathleen Sebelius and actress Linda Carter has helped singer Mary Wilson serenade congressman John Dingell in a ceremony honoring the longest-serving member of Congress.

Around 400 lawmakers, former colleagues, lobbyists and others paid tribute Thursday to the 86-year-old Michigan Democrat in a reception in the Capitol's Statuary Hall.

Dingell has served more than 57 years in Congress. House Speaker John Boehner toasted Dingell as a true man of the House.

Also speaking was Vice President Joe Biden, who lampooned his own reputation for long-windedness by warning the audience to sit.

The show was stolen by Wilson, an original member of The Supremes. Her numbers included "Stop in the Name of Love" with backup help from Pelosi, Sebelius, Carter and others.
