What 1969 musical title figure is told he's "really made the grade, and the papers want to know whose shirts you wear"? Ground control to Major Tom! History does not record whether the good Major wore Gant or Van Heusen or what.
The question refers to Major Tom as a "1969 musical title figure," but the 1969 song in which he appears is called "Space Oddity." I don't think Major Tom showed up in a song title until Peter Schilling recorded "Major Tom (Coming Home)" in 1983.
