He has been replaced by Simon Wright ex AC/DC. For the Aussie rockers he played on both the underrated 'Fly On The Wall' (1985) and the overrated 'Blow Up Your Video' (1988). He also contributed to three songs on 'Who Made Who' (1986).
As a related comment since we're talking about AC/DC ..... the new LP 'Ballbreaker' is a class album ! A personal fave has to be 'Boogie Man'. If you haven't heard the album and you like classic AC/DC then I reccomend it !
