The DeFranco Family, a pop music group from Port Colborne, Ontario, Canada, consists of siblings Tony DeFranco (lead vocals), Benny DeFranco (guitar), Marisa DeFranco (keyboards), Nino DeFranco (guitar), and Merlina DeFranco (drums). Born to Italian immigrant parents in the 1950s, they initially performed as the DeFranco Quintet. Their breakthrough came when a demo tape was heard by Sharon Lee of Tiger Beat, leading to an audition in Los Angeles and subsequent signing with Laufer Entertainment and 20th Century Records. The group's debut single "Heartbeat - It's a Lovebeat" reached Number 1 on WLS for five weeks, number 3 on the Billboard Hot 100, and sold over two million copies. Their follow-up hits included "Abra-Ca-Dabra" and "Save the Last Dance for Me". The DeFranco Family appeared nine times on American Bandstand with Dick Clark and had notable television appearances including Dinah! and The Mike Douglas Show. Despite their early success, the group's career declined in the mid-1970s due to changing musical trends and Tony DeFranco's voice changes. They continued touring until 1978 and reunited for a concert in 1999. The family disbanded in 2000 but remained close, with Tony and Marisa occasionally performing.
