What was English rock group Supertramp's biggest hit single?

Supertramp were an English rock band formed in London, England in mid 1969. Marked by the individual song writing of founders Roger Hodgson (vocals, keyboards, and guitars) and Rick Davies (vocals and keyboards), they are distinguished for blending progressive rock and pop styles as well as for a sound that relied heavily on Wurlitzer electric piano. The group's line-up changed numerous times throughout their career, with Davies being the only consistent member throughout the decades.

"The Logical Song" is a song by English rock group Supertramp that was released as the lead single from their album "Breakfast in America" in March 1979. It was written primarily by the band member Roger Hodgson, who based the lyrics on his experiences being sent away to boarding school for ten years. The song became Supertramp's biggest hit, rising to No. 7 in the United Kingdom and No. 6 on the US 'Billboard' Hot 100 chart. In 2001, a cover version by the band Scooter returned the song to the top 10 in several European countries.
