Thanks to Stefan Lindberg for pointing me in the direction of :- http://www.codetapper.com/amiga/random-rants/defaced-credits-in-the-end-sequence-of-sdi/ This has given me valuable composer information which created a chain reaction culminating in  the following tunes having correct info's or ripped :- Predator - credited to Paul Summers Everton FC - credited to Paul Summers , Mike Chilton removed P47 Freedom fighter  - credited to Paul Summers , Mike Chilton removed SDI  - credited to Paul Summers Sonic Boom - credited to Paul Summers Fighting Soccer - New Rip - credited to Paul Summers Matrix Marauders - New Rip - credited to Paul Summers Stryx - New Rip - credited to Paul Summers that just leaves Super Hang On in the Source folder. I need to investigate that driver more closely looking for similarities with SDI. Though I'm pretty sure it is also by Paul Summers.
