December 2010 saw the first appearance of new Ultrasound recordings - a cover version of the Cardiacs song "Big Ship" which was included on Leader Of The Starry Skies: A Tribute To Tim Smith, Songbook 1, a fundraising compilation album to further benefit the hospitalised Tim Smith. In the same month, Matt Jones left the band for a second time (this time amicably), opting to continue as the touring keyboard player for Beady Eye as well as concentrate on other projects. He was replaced as Ultrasound's keyboard player by former New Mastersounds member Bob Birch.
