HI Marc, all,
               The phenomenon is reminiscent of the (triboelectric?) 
charge stored in TC secondary insulation in many respects. I too have 
experienced it. Storage in the glass maybe.
     I can't account for the compass observation (your magnetic 
personality perhaps? :) but there must be a rational explanation - 
speaker in a cellphone or something like that? Lead isn't a 
magnetically active material as far as I'm aware.

Regards,
malcolm
