A childhood belief about misheard lyrics

Theres a punk song called "Ruby Soho". In the song the lyrics go "He's singing and she's there to lend a hand, He's seen his name on the marquee but she won't ever understand" I misheard the lyrics as "He's single and she's down giving head , He's seen this dame at the market and she won't ever understand" I found out the real lyics after embaressing singing mine in front a old friend. I now know. In my defense the lead singer has a very rough, slurry voice and he's hard to hear right a lot.
