I have a somewhat sheepish confession to make. Now bear with me, but the first time I heard The Smiths I was not impressed. The track I’d stumbled across was Some Girls Are Bigger Than Others, a quirky little tune that appeared as simplistically self-explanatory as its title suggested. ‘‘Some girls are bigger than others’’ sings front man Morrissey, ‘‘some girls’ mothers are bigger than other girls’ mothers’’. Scratching my head, I couldn’t decide whether or not the whole thing was a joke, the singer’s deadpan vocals giving nothing away.
