There are two key musicians behind the Polar Primates success Raz, the lead singer, who generally composes the music and Rash, who writes the lyrics. In the early stages of the bands career, they recorded a song entitled Ocean waves with a small record company. During the rehearsals for the recording, another member of the band, Gryll, introduced a bass riff. The band decided to include that riff in the recorded version of the song and it has remained part of the song. Gryll has now approached Joe, the bands manager, to assert his rights in relation to the bass riff. Identify and explain any legal rights arising in the song, commenting on any issues of ownership.
