Went to the Manchester gig last night and saw the merch for myself. There are no Defenders of the Faith shirts or merch at all. The shirts that people have seen are bootlegs from outside. What they do have though is as follows:
Opeth
Skinny T-Shirt With Opeth logo on front on shiny green letters and watershed.
A Hoody.
A long sleeve shirt with opeth logo on front.
An opeth shirt with a new scene off the new album - a house etc.
The one i got which has the new album cover on the front and dates on back
Opeth 'O' wristband.
Signed Roundhouse Tapes CD - which i also got due to the fact they were only £10!! I already have the CD but at that price signed i thought a bargain! They did sell out of the allocation for the night quite quickly though.
All t-shirts £15 and skinny £20 - don't know how much t-shirts increase to in London though if at all.
