Well fame is a tricky thing. Tommy gained a place in the spotlight once again (to AMIT spotlight), thanks to his comments and not his actual work. It was the peculiar guy that kept dancing even during Private investigations! Come to thing of it, the camera was very shy on him. We never saw him from up close. And he was part of one of the most sickening songs ever "Everything i do i do it for you".
About Jack Sonny, I don't know what you say but from the last BIA show until the recording of OES it was almost 5 years. Life can surely change lanes in such a long period.After all DS were on a hiatus. I remember MK saying in 1989 that he doesn't even think of recording again with DS. He was always busy, touring with EC, charity, awards, divorce, producing and playing on other artists' records, writing film music and probably taking sometime off. He was doing a one man's work. Then he used Phil Palmer, from EC band because he probably had spent more time together playing, so the interaction and response between them would probably mean less time rehearsing, understanding and "getting in tune". I don't think that there is something more than that. Maybe after 20 years (just around the corner) he might do a gathering of all the musicians and do a record like the Noting Hillbillies. Come to think of it, it is too bad that neither Brendan or Steve ever made it international big.
