The Dells are an American R&B and crossover musical group. Their successful recordings spanned more than four decades. Formed in 1952 after attending high school together, the Dells' repertoire has included doo-wop, jazz, soul, disco and contemporary rhythm and blues. Unlike many of their contemporaries, the group's lineup did not change much from 1960 and consisted, until 2009, of falsetto leader Johnny Carter (died August 21, 2009), baritone lead singer Marvin Junior and background singers Mickey McGill, Verne Allison and Chuck Barksdale. The Dells are 2004 inductees into The Rock And Roll Hall Of Fame, and were inducted into the Vocal Group Hall of Fame the same year. One of the longest-running groups in music history, the Dells recorded and performed for almost 50 years without a single change in personnel.
