Anon was one of two bands made up of pupils from Charterhouse School in Surrey, whose members went on to form the progressive rock band Genesis with another band from the same school, called Garden Wall.  The band formed in May 1965 and split up in December 1966.  It originally consisted of Rivers Jobe (bass), Richard Macphail (vocals), Anthony Phillips (lead guitar), and Rob Tyrell (drums).  They were later joined by future Genesis guitarist/bassist Mike Rutherford on rhythm guitar.  During a short period of time, Rutherford was forced to leave the band by his house master at Charterhouse and was replaced by Mike Colman. The Split Squad is a Rock and Roll band composed of Clem Burke (drums), Michael Giblin (bass/vocals), Josh Kantor (keyboards), Eddie Munoz (guitar/backing vocals), and Keith Streng (guitar/vocals).  Each member came to the public's attention as a member of another band, "e.g.", Burke is in Blondie, Giblin founded the Parallax Project, Kantor is in The Baseball Project, Munoz is in The Plimsouls, and Streng is in The Fleshtones.  Since many of the members of the band follow baseball, this led Annie Laurent Streng, Keith Streng's former wife, to propose the band's name.  The term refers to the practice, during Major League Baseball's Spring training, of teams often playing "split-squad games".  This occurs when a team splits into two sub-teams, or squads, and each squad plays a game against another team on the same day.  In addition to touring on both coasts, Canada, and Europe, the band's debut album, "Now Hear This..." was available for sale at shows in late 2013, and officially released through the usual online vendors in CD format on January 21, 2014.  The album was released on vinyl in time for Record Store Day - April 19, 2014.
