Amazon (UK) has the Japanese release (including bonus tracks) of Dynamite available for pre-order. Comparing total prices including shipping to the UK (apologies to all the non UK readers!), buying from Amazon is around £6 less than direct from HMV.co.jp. Amazon.co.uk currently has the release date listed as 11 May, although this is almost certainly a mistake.
The title track from the first album, Emergency On Planet Earth was released in the UK as a single today in 1993. In 1998, Deeper Underground dropped 4 places today to number 9 in the UK singles chart.
