Not sure which category to put this in, I'm sure Kewpie or other will attend to it.
Recently a printed sheet of music for 'Everyday Is Like Sunday' appeared on ebay bearing the 'signatures' of Morrissey and Johnny Marr.
Both signatures were fake.
There are many similar items still on sale, be warned.
Johnny Marr has confirmed this with me today.
Also beware of guitars that are sold as having belonged to Johnny.
