...WhiteNoise....that is absolutely untrue about THE SEX PISTOLS....everything they ever recorded was played by the band....no studio musicians subbed in for anyone....for the songs that were not recorded with Glen Matlock(..before he left...), Steve Jones played the bass parts on his guitar to cover for Sid's deficiency at bass. Vicious was not as bad a bassist as he is been blamed for.....he played bass in FLOWERS OF ROMANCE, his first band with Keith LEVENE and if you listen he actually is decent sounding(...he was just so fucked up on whatever the drug of the day was...). By the time he joined THE SEX PISTOLS, he was dope-fried and was rarely able to function as a bassist or human much of the time.
