Wheel In The Sky High Note

OK, 2 questions. I'm no voice major, so is the famous high note in Wheel In The Sky during the guitar lead sung in falsetto by SP, or is at the top of his full voice range?
I've been listening to it a lot lately and can't tell. His range was so high then, I can't be sure.
Also, on the re-records on Revelation, the note sounds the same. Is that Arnel, a spliced in SP or what? Arnel's voice, although spectacular, doesn't seem to have THAT kind of range on the rest of the record.
No matter our differences, no matter our opinions............. I just friggin' love Journey. SP is the best rock singer of all-time to me, but thank God the Journey continues.
I'd rather it be with SP, but I'd also rather it be with Arnel than not at all. Those songs NEED to be heard by this generation of young people and musicians.
