Glad you enjoyed them Rocket Dog. I certainly did.
I put them into a Pro Tools project and took them round to a friend's studio this morning and conned him slightly by asking if he could show me how to tidy up one of my early song efforts.

I told him he'd probably notice quite an improvement in my vocals since last time he heard them.....
So he walked me through various ways to prepare and set up a project properly, while I waited increasingly impatiently for him to hit the play button...
Then he demonstrated something by soloing the kick drum... which doesn't give anything away. After about ten minutes he finally played the lead vocal track and twigged what was going on.

But to my considerable astonishment he then proceeded to apply a variety of massages, using some very impressive plug-ins, and considerably improved the sound quality of the bass track and some of the drum tracks.
As he went through the process he explained what some of the possibilities were and what the pros and cons of the decisions might be, and so on. I learned a lot about recording and mixing in general, and about how one might go about making some of the mixing decisions. We just scratched the surface, but it was absolutely fascinating.
All in all, it was a great lesson, and a real treat to be able to use such terrific material for the lesson. I must admit I'd not thought about how long ago they were recorded and it hadn't occurred to me that some aspects of certain tracks might actually be improvable using modern techniques. He didn't touch Freddie's vocals though, I guess some things are still sacred!
Cheers,
