Fans had chosen the list of songs to be recorded acoustically � but Myers last month confirmed that Bon Jovi were amongst those unhappy with the project, and wouldn't let them use a cover of Wanted Dead Or Alive.

The plan was for each song to be accompanied by a video � and Smith says that's where problems arose. He explains: "Some of the artists were cool with letting us put them up on YouTube and show the video of the song being records. Some weren't cool with the video, and that's totally their decision."

Along with the Bon Jovi song, Phil Collins' In The Air Tonight, Pearl Jam's Black and Adele's Someone Like You won't appear. The pair still hope those covers can be released in audio only over the coming months.
