AC/DC - Whole Lotta Rosie

The song is about an obese woman, Rosie, (physical measurements: 42"-39"-56" and weighs nineteen stones (120 kilos)) with whom the singer (Bon Scott) has had sexual relations. In addition to pointing out the woman's obesity, the singer finds her to be one of the most talented lovers he's experienced - note the solo at the end.

There is an ongoing search for the real Rosie, although she has yet to be found!
