In the mid 1930s, the zoo portion of the park was discontinued, with the space being used for more formal gardens (and rides). A giant floral clock was added and the Trocadero Ballroom became a regular stop for touring big bands and home to "An Evening at the Troc", a weekly radio broadcast. During this classic period of Big Band Jazz and Swing, the Trocadero Ballroom became a famous summertime night spot as its seemingly endless succession of brilliant stars provided countless hours of live national radio broadcasts in an age before television.
