Sofia - Search & Destroy

Have you ever thought about what Johnny Thunders had spinning in his mind when he wrote "Chinese Rocks"? What is actually a "streetwalking cheetah" depicted by Iggy pop in the song "Search & Destroy"? What is Phil Lydon of Sex Pistols mouthing of about in the song "Pretty Vacant"? Did the fact that Pete Shelley of Buzzcocks was homosexual have any resonance in his lyrics?
