Hello, hello, hello. Hello. Hello, I’m Bob Smith. We’re in my studio in the East End and I’m working on a project which is the Christmas tree for the Tate this year with Tim Siddall, who has this project called Electric Pedals; and we’re going to make our own power for the Christmas tree, and we’re going to be encouraging people to make their own Christmas trees. TIM [Song] I went to the shop to buy some buns. I said, can I have 24 iced buns, please. TIM It’s good to see you’ve got such modest surroundings, Bob. BOB Yeah, thank you very much, yeah. TIM You’re keeping it real. BOB Keeping it real, yeah! [Laughs] Unfortunately, yeah. It’s all too real. BOB I’m making signs for the Christmas tree which exhort people to make their own Christmas, make their own food, make their own fun. TIM [Song] I said, no, we don’t need DJs. [Singing] Because I can sing and play the guitar at the same time. Watch this. BOB They’re all painted on recycled estate agents’ boards. Obviously we’re in a bit of a period of austerity. And they’re going to hang off the Christmas tree, as are the lanterns, which are also going to be made out of these boards. TIM [Song] I really wanted some chicken curry and rice. [Music] I knew I’d have to have a chicken sacrifice. BOB And the tree itself is all made out of recycled materials from Tate Britain, and they are all materials that have been used in exhibitions at the Tate in the past. Like these gels here, which are in the… these are all from the Tate. So we’re trying to recycle all the backstage bits and pieces of the Tate, basically, to make the tree, with power generated by people on bicycles. TIM You can use any bike, and it’s just on a stand at the back, and there’s an electric scooter motor attached to the back wheel, which when you turn it, works like a generator, and it generates DC current enough to power music, lights… It’s brilliant. Make your own stuff, power your own lights. People will love it. BOB Yeah, see my face light up. [Laughter] That Christmas morning look! TIM You know, you could put a microphone on the front, you can play while you’re pedaling and run a little amp. [Music] Because you can sing and play the guitar at the same time: watch this. BOB On the tree there will also be incident tape bunting. I’ve been collecting incident tape, and we’re going to wrap that round the tree as well, so I think it’s going to be fun. I think it will make people laugh. [Prolonged laughter] TIM It’s all right! BOB [Laughter] I’m just trying to… [laughs] Sorry… Oh dear oh dear… [Christmassy music] But I think what might be quite interesting is to ask people there what their favourite memory of Christmas, but also ask them what the most dismal aspect of Christmas has been for them. VOX POPS My worst Christmas memory, trying to keep various grannies happy whilst also nipping out for a smoke at the same time. Probably Christmas morning hangovers where you can’t even face your Christmas dinner! Probably being in Poland, and being stuck in the airport. That was pretty rubbish. I was eleven. I didn’t enjoy that much. My dad bought me a wooden bingo set… pretty bad. My favourite Christmas memory, walking with my dog Jake when I was a kid through the snow, back home in Sussex. Cooking Christmas dinner one year when there was no power, and having to cook legs of lamb on an outdoor fire. That was good. I think it’s going to be this, actually – sweating slightly at Late at Tate, helping save the planet!
