To the best of my knowledge, the first 2, Gentle Giant & Acquiring the Taste
are owned by Vertigo UK, and the 3rd & 4th, Three Friends & Octopus are owned by Vertigo UK and Columbia USA. Civilian is owned by EMI Capitol but i don't think the band wants to reissue it because it is not very good! Just like the last set of reissues these titles were not released. I have the first 4 on Japanese pressings and they sound very good, but are expensive!
