I'm not sure if this strip was published. It seems unlikely it was because the IPC lawyers hated drug references. However the snow is seasonal and of course the Ice Queen reference means it was drawn when Thatcher was in office.  

The date this gag was published is also obvious, but off hand I can't remember when ET came out. Interestingly dope references were easier to get into cartoons than harder stuff. There was even an NME front cover with a Benyon drawing of a dazed looking Art Garfunkel with a thought bubble saying something like "I sure smoked too much dope".

Getting back to the Bakerloo Blues Line. The drummer, Keith Baker, played briefly with other bands while he was living with Benyon. Uriah Heep was one and the other a band called Daddy which changed its name to Supertramp but he didn't stay long with either band for different reasons. I seem to remember Keith's girl friend smacking Heep's lead singer across the face because he was swinging his microphone stand too near to Keith's drums, which hadn't been paid for. The BBL guitarist was Clem Clempson who went on to play with Colosseum and then Humble Pie

I went to the flat quite a few times during the May Blitz period period and I remember Benyon talking about the Album Sleeve. The record company, Vertigo, was also putting out the first Black Sabbath album featuring a mysterious, cloaked female. Evidently it was supposed to be nude shoot but the morning was freezing and the model refused to disrobe and wanted to keep her cloak on. I watched a Sabbath documentary on the making of that album and they talked about the cover but missed the story, but rock documentaries are usually incomplete or one eyed. Oddly enough Bakerloo Blues Line were a midlands bans and knew Sabbath really well from their days as a band called Earth and they had a lost of excellent Ozzy stories, none of which appeared in the documentary.
