Joop de Korte said to me by mail that during the OES sessions, and tour, MK wanted to go 110% proffesional, so they tried many musicians, and he was out of the band as percussionist, as MK wanted "a proffesional percussionist" instead of him, playing percussion for Dire Straits since 1980 behind the curtains...
I guess that MK thought that the right attitude in that case was having an assistant to deal with the proffesional musicians, so thats why he didnt talk to Manu, and probably to the other musicians.
Phil Palmer and Danny Cummings were other two proffesional musicians that played on the record, and apparently got the invitation by MK (probably via the assistant) to tour with DS.
I think that those years were difficult to MK, Joop de Korte also said to me that MK looked very very bored and tired since the very beguining, and everybody was very happy when the tour was over.
