Rimmer joined the band in March 2013 to replace John Jowitt who had been a touring member since January 2013. Jowitt filled in for long-time bass guitarist Trevor Bolder who had to give up touring because he was suffering from pancreatic cancer. Rimmer became a permanent member in Heep after Bolder passed away in May 2013.
