First rap ever? Maybe. Best Italian 1972 single not included in a 1972 Long Playing? For sure.

"Prisencolinensinainciusol" [prizenkolinensinainˈtʃuzol] is a song composed by Adriano Celentano. It was first released as a single on November 3, 1972.

“Ai ai smai senflecs / eni go for doin peso ai/ in de col mein saivuan/ prisencolinensinainciusol ol rait”
