when my dad gave me the guitar 
he wasn't using anymore.
Der Auslöser war, als mir mein Vater
seine Gitarre gab, die er nicht mehr brauchte.
quand mon père m’a refilé
sa vieille guitare.
quando mio padre mi diede
 una chitarra che non usava più.
quando ganhei o instrumento
que meu pai não usava mais.
Начал из-за того,
что отец отдал свою ненужную.
