Stuck on the Jubilee Line travelling westbound towards London Bridge, I noticed a group of people in orange/yellow high visibility vests including one holding and aiming a TV camera and another with a sound/microphone boom.
They were in the bit between the westbound/eastbound platforms where I think there are stairs or something coming down onto the platform. This was around 1545; they were not there at 1640 or so when I went back the other way.
Locations and times are approximate. Did anyone else see them? And what were they doing? A couple also had clipboards I think.
(OT - Reminds me: a couple of days ago when every ten meters or so around Bond Street station there were people with handheld clicky counters, clipboards and high vis vests, particularly at platform level and in all the interconnecting bits.)
Just been watching the music video of 'Back Here' by BBMak. It seems many of the Jubilee Line scenes were shot at Southwark station, evidenced by a brief reflection of the name - reversed, naturally - in a shot of a pair of closing Platform Edge Doors.
However, this pre-dates the filming I mentioned by three years, since the music video was produced in 2000.
