Northern Irish rockers Ash have fuelled speculation they are to split after the release of their fifth album later this year (07). Guitarist Charlotte Hatherley quit the band in 2006, but the group have performed with their original line-up of Tim Wheeler, Mark Hamilton and Rick MCMurray ever since. But Wheeler told the audience at last weekend's (08-11Jun07) Isle Of Wight festival, "This is our last song off our final album," referring to the group's new release, Twilight Of The Innocents - which is slated for release in July (07).
