Has the Big in Japan - Alphaville vocal been created with Varispeed?

This is a live a version. Vocal still looks played back.

Hard to explain why but by comparing voice timbre and speed of expression with image brings to mind Varispeed processing while vocal had been recorded at the studio.


Or playing back recorde tape at slightly higher speed when master tape had been created by re recording.
