In Jamaica, Branson met with members of the band Devo, and tried to install Rotten as their lead singer. Devo declined the offer, which Rotten also found unappealing.Cook, Jones and Vicious never performed together again live after Rotten's departure. Over the next several months, McLaren arranged for recordings in Brazil (with...  answer the following question:  What is the full name of the band that split on 17 January?
