Just found this thread, as bit late!
Watching BBC2 late night education TV recently (the schedule says it was on between 02:00 and 04:00 on 27 May 2007) I saw a series of programmes about making things which must be part of a schools design and technology course. The series is called "Techno - Making It" for 11-14 year olds. The items were quite short, about 20 minutes. The first was about go-carts and the second was about bass guitars, the item was called "The Bass". And lo, who should be featured but Martin Petersen and Chris McIntyre making a SeiBass for a young female bass player (Yolanda?). Must have been some time ago because they both look like teenagers (to me) and I know Chris left The Gallery 3 or so years ago. Sadly I've failed to find any more details on the BBC website, but it's out there somewhere! Nick S
