Ridge Bond, the Broadway actor who helped make "Oklahoma" the state song, is tuning up his vocal cords to help celebrate the song's 50th anniversary.

Bond has sung the title song from "Oklahoma!" between 2,000 and 3,000 times. He was the longest-running Curly in the Broadway play, performing from 1946-54.He sang it again Tuesday at a luncheon in Oklahoma City celebrating the release of a commemorative stamp on the play's 50th anniversary, which is Wednesday.

Bond, now an insurance executive, sang the Rodgers and Hammerstein song at the state Capitol in 1953 to help former Gov. George Nigh make it the state song.

"If I might have sung lousy, it might not have passed," he said.
