On the evening of the thirty-ninth annual Grammy Awards that was broadcast on national television on February 27, 1997, Colin Dunn and Savion Glover faced off in the fiercest tap dance challenge of their lives. Colin Dunn, the star of Riverdance\u2014The Musical, was challenging Savion Glover, the choreographer and star of Bring in 'da Noise, Bring in 'da Funk, to a battle of the feet that was staged to showcase and celebrate the two hottest musicals on Broadway. But there was nothing festive about the challenge dance for these two stars. Not only was their reputation as dancers at stake but also the supremacy of the percussive dance forms that each show represented\u2014Irish step dancing and African American jazz tap dancing.
