Мы бандито и Elvis - плагиат или случайное совпадение

Давайте сравним две песни: 1) “Мы бандито, гангстерито“ муз. Г.Фиртич, сл. Е. Чеповецкий - м/ф “Приключения капитана Врунгеля“ 2) “Somos Novios (It's Impossible)“ is a song written by the premier Mexican bolero composer Armando Manzanero. The song was translated into English by Sid Wayne and first recorded by Perry Como in 1970. It is one of the most popular boleros of all time. Besides Como, it has been recorded by Elvis Presley, Andy Williams, Jerry Vale, Dennis Brown, and Andrea Bocelli. Tejano group Mazz recorded this as part of a meledy entitled “Canciones De Amor“ which was on the album Para Nuestra Gente. Что это - плагиат или случайное совпадение?
