On the original recording, the 1:54 minute instrumental piece entitled "Sirius" immediately precedes, and segues into, "Eye in the Sky". On the single release, "Eye in the Sky" appears on its own, with "Sirius" edited out; that was the version usually played on pop radio at the time. However, album-oriented rock and classic rock stations now almost always include the "Sirius" intro.
