Thanks for all the help.   I'm finally getting back to working on this.
First....using a Audacity I was able to read in the album version of Blue Moon and shift it up a half step so it is in tune with the guitar.....I can also slow it down without changing pitch.

The recorded lead that Bob plays is different than the one he plays in the youtube video posted above.   I find the album version harder to play and like the live version better.
The tab for the recorded verse is something like:

E)------------------1--1----0--------1-1---0-------------------33333---|
B)------------------1--1----1--------1-1---1-------------------33333---|
G)-0----0-0-----0-2-0--0----0--------0-0---0----------------2--44444---|
D)--3-2-------3----------3--2--0-2-3-----0-2-----0-2-----------55555---|
A)----------~----------------------------------3----3-3-0-3------------|
E)---------------------------------------------------------------------|


WHereas tab for what he's playing on youtube is something like:

E)-------------------------------------------------------------33333---|
B)-------------------------------------------------------------33333---|
G)-0----0-0-----0-2-0--0----0--------0-0---0----------------2--44444---|
D)--3-2-------3-----2--2-3--2--0-2-3-2-2-0-2-----0-2-----------55555---|
A)----------~----------------------------------3----3-3-0-3------------|
E)---------------------------------------------------------------------|



I/m not great at tab so please see it only as a guide and correct me where I'm wrong.

Also from the youtube version ,   watching Don play the chords for the lead in he is playing C - Am - Dm - G...........which is interesting because the lead plays F where he  plays Dm.

I'm working on tabbing out the solo and will post it when I complete it.   The solo uses a lot of open strings.    On the recording for the 2nd time through when they move up one step, he must have put a capo  on the 2nd fret....only way he could have played the solo.   Makes me wonder if they used capos a lot.    I wonder if they used it to play the lead on Perfidia for the 2nd time through.

well...that's my update for today
