The one thing for sure is that there were, over the years, a lot of personnel changes with not only the Blur Boys but Wagon Masters as well. From what I found from the Internet and also Larry's book shows a picture of constant changes in band members and I guess this leads to a lot of confusion to keep it all in order.

I want to quote here from what I found so far.
"The Blue Boys were Jim Reeves road band and at different times various personnel. Initially Reeves' called his band the wagon Masters, but to avoid confusion in Nashville with Porter Wagner, he renamed it in 1958 The Blue Boys. The band initially comprised of Billy Harlan (bass) Royce Morgan (guitar) Jimmy Day (steel guitar) and Pee Wee Kershaw (drums). Until shortly before the new name, Leo Jackson was Reeves' lead guitar but at the time of the formation, he was doing military service and Morgan took over. About a year later, Reeves changed the band and saw appearances from James Kirkland, Henri Strzelecki, Mel Rogers, Bobby Dyson and Roy Aldridge, he ended with a line up that featured Leo Jackson (lead guitar) Dean Manuel (piano) Bud Logan (bass, vocals) and Jimmy Orr (drums)."....end quote.

Mike you mentioned Floyd Cramer but oddly his name does not appear which is strange. I think you may be right but where exactly he contributes is not mentioned. And where does Buddy Killen fit in as Gary mentioned. Can any one help here ?

Well I hope this is not too confusing, and really hope this is somewhat correct. If anyone can add or correct what I posted, please do so. Main objective is to get this right but obviously can be challenging to say the least....
