Never saw a BIA record where Hal Lindes is credited...
Actually Hal Lindes rehearsed with the band before going to Montserrat, and he went to Montserrat. But being there, it was the end. John Ilsley said in his "DS Q&A tour" when a Lindes pic was shown at the screen that "When he left everything went quiet" so I guess there was any kind of argument, maybe he wanted more presence... Maybe thats the reason why he started a career doing music for films.
