Hi Andreas,
Firstly a very Merry Christmas to you and your girlfriend, from the very fast speaking Englishman! Have a good one! I've got that copy of the mag and I am only guessing, but knowing John these songs probably changed names during the creative process - therefore maybe 'The Sky' became 'The Lifting Sky' (a personal favourite cos I can play the guitar riff!), and I suppose we could all take a guess at 'My City...' it could be one of the many 'City of Light' songs, I would again guess at the one that is a B-Side from the IMW singles.
Cheers
