The music to Somewhere over the Rainbow was written by Harold Arlen; the lyrics were written by Edgar Yipsel (Yip) Harburg. But Julie Garden sang it. Arlen and Harburg collaborated on all the songs featured in the movie, The Wizard of Oz. Over the Rainbow won Academy awards for them both.
Perry wrote the lyrics, in which he expresses the sadness of being on the road and away from home, while also expressing admiration for the band's fans, and Schon wrote the music for the song. Other popular singles included Lights and Wheel in the Sky. The latter was co-written with temporary frontman Fleischman. Journey's manager, Herbie Herbert, enlisted English producer Roy Thomas Baker to engineer Infinity.
