Here’s an interesting interview with Andy from the Dublin Evening Herald; which reveals (amongst other things) that ‘House Of Mirrors’ was partly composed by accident!
“House Of Mirrors nearly didn’t make it on to the album because we couldn’t end it. Fortunately, Dan [Austin] was messing around with Pro Tools in the studio, and accidentally put the verse vocals over the chorus music.
“We all heard it and said ‘That’s it! How did we not think of that?’ That’s where technology can really help you out.”
