Thanks to George from BARROWMANONLINE, we have this message from John's manager, Gavin:
"John Barrowman is going to be on GMTV this Wednesday (23rd July) - a live link from LA - to discuss 'The Making of Me'. It'll be his only TV
interview for the show - and they're the only show who regularly do live links to LA. It's due to air at 7.40am and then again at 9.10am."
