I'm thinking of two examples of a Dsus. One is the opening to Neil Young's "When you Dance"; another is "Moonshadow". I'm sure there are tons more (I Need You - Beatles) but the important thing (Carry on - CSN&Y) to remember in this possibly overworked (Stairway to Heaven - Zepplin) chord is playing a standard D chord with an (Hold your head up -Argent) added G note on top of the chord--usally with the pinky. Oh somebody mentioned "Pinball Wizard".
