This has to be one of the most audacious follow up singles ever made. People who loved "Rudi's In Love" must had been baffled when they heard this since it sounds like a completely different band altogether. Great record!
It's appeared many times on compilations usually in stereo. On the album they released a few months later, it was preceded by a two minute orchestral medley of themes from the album, so most times on compilations, it fades in just as that medley is about to end. The mono single version on the other hand has a totally unique "proper" intro that was not used on the album stereo mix. Though it is available on CD, most people are familiar with the stereo mix which though superb, is not quite the same as the single thanks to that unique intro.
