Frank Sinatra Jr dies on tour

Los Angeles: Frank Sinatra Jr, the son of legendary singer Frank Sinatra and an artist himself, has died. He was 72.

The Sinatra family said in a statement that he died of cardiac arrest while on tour in Daytona, FL, and that they mourn the untimely passing of their son, brother, family, and uncle, reported RollingStone magazine.

Though his father may have discouraged his son from going into the music business due to its challenges, Sinatra Jr followed in the footsteps of his famous father as well as worked by his side.

When he was 19, he was kidnapped and held for ransom, though he was released a few days later and the kidnappers were caught and convicted.

He later became his father's music director and at the age of 44 began serving as his father's conductor. His debut album, 1965's "Young Love for Sale", was understandably influenced by his father and was also released on Reprise, which was also his father's longtime label home.

He was scheduled to perform at The Peabody Daytona Beach, which was billed as "Frank Sinatra Jr.: 'Sinatra Sings Sinatra' The Centennial Celebration," according to Ticketmaster.
