I honestly didn't think SV was ever straight enough, long enough to actually record the lyrics to a complete song
You are correct. He seldom was. "My Way" was produced for the film "The Great Rock and Roll Swindle", and was Sid's high point as a solo performer. He never actually recorded an album, and it was fairly common to turn his amp off when they played live, simply because no bass was better than Sid's bass.
BTW: Who are "Kevin Smith ... Jason Mewes"?
Kevin Smith is the director of "Clerks", "Mallrats", "Dogma", "Chasing Amy", and most recently "Jay and Silent Bob Strike Back". Jason Mewes is his profane man-child sidekick. They're better known and more easily recognized as their alter egos "Jay and Silent Bob". The deal is that (in character) Kevin almost never talks, and Jay never shuts up. Kevin, however is the one who writes all the dialogue, and Jay, well, there's a reason all his films have someone assigned to be "Mewes Wrangler". The front page of the website has a pretty fair depiction of how the work load is divided. Put it this way: Kevin Smith is currently in post-production on his 6th feature film, and is in pre-production on #7. Jason Mewes is in rehab trying to quit heroin. Get Well, Jay!
