"Rosanna" is a song written by David Paich and performed by the American rock band Toto, and is the opening track and the first single from their 1982 album Toto IV. This song won the Grammy Award for Record of the Year at the 1983 ceremony. "Rosanna" was also nominated for the Song of the Year award. It is regarded for the half-time shuffle which drummer Jeff Porcaro developed for the song, and for its production: it is generally seen as being one of the best mastered songs of all time. The groove has become an important staple of drum repertoire and is commonly known as the "Rosanna shuffle". Record of the Year at the 25th Annual Grammy Awards, February 23, 1983 — hosted by John Denver at Shrine Auditorium. Wiki link Wiki link
