The '70s Philly disco vocal group First Choice's first big breakthrough was the infectious "Armed and Extremely Dangerous" (with its urgent "calling all cars!" intro), a Top 20 R&B/Top 30 pop hit in 1973. New attention was brought to the female trio when Mary J. Blige did a faithful cover of their dance classic "Let No Man Put Asunder" in 1999. Lead singer Rochelle Fleming, Joyce Jones, and Chester, PA, native Annette Guest were originally known as the Debonettes and performed around Philadelphia. Radio DJ Georgie Woods introduced them to Philly soul guitarist/songwriter/producer Norman Harris, who produced the debut single "This Is the House Where Loved Died," which received airplay in Philly and other markets but failed to chart nationally.
