Let's Go (Pony) is a 1962 song by The Routers. Its infectious “clap clap clap-clap-clap clap-clap-clap-clap Let's Go!" chant became a favorite of cheerleaders and crowds worldwide.
Although the songwriting credits are given to local singer Lanny Duncan and his brother Robert Duncan, Lanny had previously recorded the original demo of the song in 1961 as a member of the Starlighters, featuring Tony Valentino on guitar and Jody Rich on bass. The demo was recorded in Glendale, California with engineer Eddie Brackett.
Chartwise, the song made #19 on the Billboard Hot 100, #27 Cashbox and #32 on the UK Singles Chart.
