Drummer Joey Kramer has filed a lawsuit over Aerosmith's decision to have another drummer behind the kit when the band performs during the Grammys ceremony. Kramer has been dealing with some injuries that resulted in the group relying on the drum tech to fill-in for him during some dates during the group's Las Vegas residency, but Kramer claims he is ready, able and willing to play the Grammy event but was notified by the band that the decision had been made to sideline him.. Responding to Kramer's suit, Steven Tyler released a statement that read, "Joey Kramer is our brother; his wellbeing is of paramount importance to us. however he has not been emotionally and physically able to perform with the band, by his own admission, for the last 6 months. We have missed him and have encouraged him to rejoin us to play many times but apparently he has not been ready to do so.
