In addition to the standard union scale fee, some performers may also negotiate additional compensation for their performance, such as royalties or a share of the profits from the broadcast. These negotiations are typically conducted between the performer's agent and the Recording Academy.
It is important to note that not all performers who are invited to perform at the GRAMMYs actually accept the invitation. Some performers may decline due to scheduling conflicts or other commitments, while others may simply not be interested in performing at the event.
