Wasn't Mike Stone listed as co-producer (I know he was a sound engineer)on NOTW and ADATR...is there any suggestion he made to the guys? How much was he involved in the creative process?
Or am I asking too much?
No, you're not.
Mike wasn't producer of ADATR, he was an engineer and sung additional vocal on GOFLB.
And for NOTW - he assisted to produce album and engineered.
Besides he was engineer for Queen II, SHA, NATO albums.
