Steven Wilson: Guthrie Govan unable to tour the US with the band.

Steven Wilson's awesome guitarist Guthrie Govan has posted the following message:

Greetings - GG here!
Just a quickie to address some recent enquiries...
Due to The Aristocrats' summer touring plans (coupled with the regrettable fact that all of my research in the challenging field of self-replication has thus far proved to be fruitless) alas I won't be able to join Steven Wilson for the forthcoming US dates of his 2015 tour.
Nonetheless, I can assure any concerned parties that my successor for these US dates will not disappoint you... I'm sure Steven will reveal more whenever he feels that the time is right wink emoticon
