Poco is a Southern California country rock band originally formed by Richie Furay,  Jim Messina and Rusty Young. Formed following the demise of Buffalo Springfield in 1968, Poco was part of the first wave of the West Coast country rock genre. The title of their first album, Pickin' Up the Pieces, is a reference to the break-up of Buffalo Springfield. Throughout the years Poco has performed in various groupings, and is still active as of 2015.

Plain Old CLR Object or POCO is a play on the term POJO, from the Java EE programming world (which was coined by Martin Fowler in 2000 ), and POTS Plain old telephone service, from the analog telephone world, and is used by developers targeting the Common Language Runtime of the .NET Framework. Simply put, a POCO does not have any dependency on an external framework.
