Anybody heard this?  I've heard about this for many years but only recently sampled some of it.  I dare say it sounded very authentic and maybe better slowed that in the tempo I am used to hearing.   I've got a few RJ CDs and I think I am going to slow all of them down.

It would be great if a professional job could be down to slow them down and maybe adjust the tempo on some of the songs that seem to slow down and speed up.
