"Emerald City" is a 1967 song by The Seekers about a visit to the fictional Emerald City from L. Frank Baum's Oz books. Set to the tune of "Ode to Joy" from Beethoven's Ninth Symphony, "Emerald City" reached #50 on the UK Charts in 1967.
The song was recorded in 1967 and released as a single around Christmas in 1967. The original writing credit was given to Kim Fowley and John Martin, but during a 1993 reunion tour, The Seekers revealed that "John Martin" was actually the pen name of band member Keith Potger.
