What group sang over the rainbow in the 50's 60's?

In the 1950s and 1960s, the iconic song "Over the Rainbow" was famously performed by Judy Garland in the 1939 film "The Wizard of Oz." While several artists covered the song during that era, one notable version was by the group The Platters, who added their own style to the classic. However, the song remains most closely associated with Garland's original rendition.
