"Zorbing" would fit well a walk outside in springtime, which I do now.
"Unfaithful" has a very nice intro. And the swings of the guitar at the end of verses; just fine.
"Here comes the blackout" refers to the July 7th bombings in London in UK. Loving your neighbour would bring peace..
"Watching birds" is inspired by Briggs' studies and is a very fun song:). It is recorded in a house, with a tape recorder. And the label liked it and didn't want a re-make.
