Of special interest is the reprise of Over The Rainbow at the end of Wizard of OZ. Broadcast Christmas of 1950 at the end of Garland's MGM period. The first time it's sung it's still very much the in character Dorothy version, the reprise however is a bridge to the version Judy would sing during her concert years.
