I've noticed that Amazon.co.uk still has Turn On To T-Bag DVD available for pre-order (with a crazy release date in 2015!), although it's not there when you search but the page is still accessible!
Revelation Films is not likely to release this individual DVD but let's all pre-order and hopefully they'll get a lot of pre-orders and contact Revelation Films which might prompt them to consider the boxset again.
I'm sure when we did this via HMV a few months ago they must have had a lot of orders. Anyway, it's worth a try again! I've pre-ordered just now, so who's with me?
