"Goodbye Mr A" is the second single by English pop rock band the Hoosiers, from their debut album, The Trick to Life (2007). The song is written in the key of B major and was created in memory of frontman Irwin Sparkes' secondary school English teacher, Jonathan "Mr A" Anderton, after Sparkes heard of Anderton's death in 2006. It has been noted for its similarities to Electric Light Orchestra's single "Mr. Blue Sky". Released on 8 October 2007, the song gave the band their second UK top-five single, entering the UK Singles Chart at No. 5 on 14 October 2007 and climbing to its peak of No. 4 the following week.
