Vocal version is pure sacrilege to the masterful original, didn't even know it existed until now. They even had to change the unique momentum of the original to make it fit. No, the vocal must not be touched.
The original is just delightful, and even when the bpm is notched up to fit in the Trance sets it can become even more enjoyable. Its such a simple track but has beautiful synths that carry it to great places.
