Are you sure about that? I don't remember there ever being a logo on the main tower, although a still of the building was sometimes shown on screen with a logo in that position.
Yes - pretty sure...
..even though a search via Google images throws up (unlike someone with Norovirus) nothing.
Inspector, in my formative years, as part of a School day out we all were packed off on a coach to go to London.
Boat trip was included, and the highlight for me was seeing Kings Reach Tower and the LWT logo at the top - although I do agree with you, there another one lower down on the podium building.
All of course is a roundabout way of finishing off the story. Back in class the next week, we had to write down our favourite buildings we saw.
Yep, every one else said Big Ben or Buck Palace - mine was LWT and Thames Television on the Euston Road (which I saw as we flashed past it on the coach belting back towards the M1 motorway.)
