I think its called Sirius. Eye in the Sky was immediately afterward when they performed in concert. I own eye in the sky on itunes and it doesn't have the intro part on it. So the song is actually called Sirius. But that's as far as I know.
It's Sirus by Alan Parson's Project. Actually, my family helped produce SunSational Sounds for the Suns in the 90's. It was a compilation album with all of the Arena songs on their in addition to Al McCoy highlights. Ouchie, I can probably get you a copy.
I remember the intro on the jumbotron that had the flaming basketball fly through the grand canyon and over downtown and fly into AWA. I loved going to those games.
An additional note:
When introducing the visiting team they played the beginning of Billy Idol's "Hot in the City".
It would be cool to have the current Suns TV theme available, it would make a great ringtone. Does anybody have it without Tom Leander talking over the music?
