Mark - you are off the mark (sorry for the pun). Neil produces all his own style files which are song specific - I have them all - Bill also produces different song specific styles - I have them all - there is NO crossover between the two.
Neil does it for a living; Bill does it for fun and in order to back singers that he works with.
Both are real genuine guys and I have the greatest respect for them both..another place to go is www.carillonstudios.me.uk for yet more fabulous style files...
