Competitors this week include a 70-year-old grandmother, on "Dance Machine," the show where ordinary people who are extraordinary dancers mambo and jive their way to cash and a coveted title, FRIDAY, JULY 4 (8:00-9:00 p.m., ET) on the ABC Television Network. Jason Kennedy of E! News is host.

Each episode features six real people from all walks of life who will face off in a series of one-on-one "dance-offs" to the most popular songs of all time. By the end of the evening, just two finalists will be left to challenge each other for the honor of being crowned that night's "Dance Machine" - and to take home $100,000 in cash. DJ Rodney Perry spins the tunes.
