my vote would go to Mancini's "March of the Cue Balls" (which has been used as a news intro/sounder)
The Westinghouse stations used it for years...Go to historyofwowo.com if you want to hear it on some top of the hour ID's.
Couple of cold vocal intros:
Beatles "When I Get Home"
Beach Boys "When I Grow Up (To Be A Man); "Good Vibrations"
And, yes, "Hush" is just made of awesome.
