Sound of Philadelphia architects Kenny Gamble and Leon Huff will be honored with the Johnny Mercer award at the Songwriters Hall of Fame gala in New York in June.

The Mercer Award, the organization's highest honor, can only go to songwriters already in the Hall of Fame. Gamble and Huff, authors of "If You Don't Know Me By Now," "Me & Mrs. Jones," "Expressway To Your Heart" and innumerable others,  were inducted in 1995. Other songsmiths going in this year at the ceremony to be held at the Marriott Marquis in Manhattan on June 12 include Ray Davies and Donovan.

“It will be our pleasure to welcome Gamble and Huff into the circle of superwriters who have received the Johnny Mercer Award,” said Hall chairman Jimmy Webb said in a statement. “They have met the standard with a series of indelible melodies and lyrics, and an enviable string of number one records and gold and platinum discs.”

The Intruders' "Cowboys to Girls," Gamble & Huff's first number one hit, is below.
