Thanks so much for all those answers. Can't believe how many ideas people have had. As a result don't think I have much to share.
I don't think the snowflakes or chimney are clues. Also I think the "white stuff" under Glastonbury Tor is just snow on the hill.
I'm thinking Spiral and I'm a Celebrity too and can't think of anything better than British Animal Honours.
Still not sure about the Microphone. While Made in Chelsea is nice, they don't tend to be that cryptic.
Also what I described as a tea caddy is that paint box with ? casino tiles and croupier stick and Prince of Wales / flour de lys.
Thanks again. Dragon's Den is a much better answer. I think Pet School is also a better answer. And I'd completely missed Royal Paintbox. Thrice ta. It's the microphone I feel least sure about.
So far only managed to find 49 clues, what have I missed out?
