“ We have all lived through that shriveling moment when a parent walks into a room and repeats, with sardonic disbelief, a couplet picked up from the stereo or the TV. 'What does that mean, then?' my mother asked me during Top of the Pops. Get it on / Bang a gong? How long did it take him to think of that, do you reckon?' And the correct answer - 'Two seconds, and it doesn't matter' - is always beyond you, so you just tell her to shut up, while inside you're hating Marc Bolan for making you like him even though he sings about getting it on and banging gongs. ”
