As the run-up to Christmas begins, the countdown the the official number one tune is heating up - and there's a surprise in store. Reverend and the Makers have took charge on the bookies' list with their Late Night Phone Call offering taking on the likes of the new Band Aid song and Mariah Carey . However, for frontman Jon McClure, his song is more than just a bid to top the charts. The band is proudly supporting the Samaritans with their song - a charity Jon, 42, holds close to his heart.
