this is when he means he's getting izzy and axl back involved for at least 1 song (izzy included coz my doubts on slash's song writing ability are quite high)
Slash isn't a bad songwriter at all, he helped write 'Locomotive' and, best of all, 'Coma', with Axl, and on his first solo/Slash's snakepit album he wrote 'Be The Ball' by himself, which is probably the best song on there.
