The Temptations' "It's Growing" features Earl Van Dyke playing a toy piano for the song's introduction, snow chains were used as percussion on Martha and the Vandellas' "Nowhere to Run", and a custom oscillator was built to create the synthesizer sounds heard on many of the later records such as the Supremes' "Reflections" and "Forever Came Today", and the Temptations' "Runaway Child, Running Wild".
