It does list what Frank was buried with...
As well as the lighter, other gifts placed in Sinatra??s casket at the interment in Palm Springs, California, included a bottle of his favourite Jack Daniel??s whiskey, a packet of Tootsie Rolls, the sweets made in his home town of Hoboken, New Jersey, and a ring inscribed with the word ??Dreams? left by Mia Farrow, the actress and third wife of the singer.
However, it is the lighter, included by Sinatra??s stepson Bobby, which has the most controversial connotations. It is now thought to be linked to the discovery of a gold lighter inscribed as a gift from Sinatra at the home of Lucky Luciano, a mafia don, in the 1970s. The incident blackened the singer??s name by suggesting he was close to the mob.
