Ah, Sheila, resplendent in her purple sequined hotpants, is having such a good time on the cover of this record with her tight-trousered pals. And so she might - for her group have made a blinding record.

She's in love, you see, and it's making her feel ill (not sleeping, sweating etc.) but this is "good" and all the disco nation roars in approval.

Perfect chirpy pop music for everyone.
