1. The reverb is very long, delayed, and kinda mid-rangy. It does sound like the high and low end has been filtered, which is why it fits into the track without being too noticeable (unless it's isolated like here).
2. This doesn't sound like there were too many takes recorded. Of course, Bowie was famous for only doing a single take on most of his records. There are some flat notes by Freddie Mercury, especially at the end of phrases, but they're not noticeable in the track with rest of the instruments (That's a good lesson for producers who beat up their vocalists).
3. There's a modulation effect on the vocals to widen them out. This might've been a Harmonizer, as this was a trick used with the device.
4. Listen how the effects are taken off the vocals during the bridge (1:43) so they're up closer in your face.
