Dunno if interesting to you, but where I live and fly, inital call is always strictly "XXX TWR, OY-YYY" and nothing else. Everybody knows what's to follow when TWR replies "OY-YYY go ahead". AC passes a strictly defined sequence of details + the request. This irrespective of what kind of station you're talking to and what kind of services it provides (TWR, APP, DEP, FIS). TWR would never ask for details unless pilot screwed up.
BTW, re "information beta", is information G then "infomation gamma" ? :-)
