I am no theatre aficionado, but I do harbour a furtive affinity for ’50s doo-wop music. So when I heard Jersey Boys was in town for a run, it took all of my masculine self-restraint not to let out a shriek of excitement. Of course I wasn’t going to ask any of my typecast South African rugby-watching mates to join me, so I went with my cultured feminist companion with whom I usually indulge my more refined pursuits.
