An example of my notes, a complete mess and with some info from Jones' bio (which did actually contradict itself in a few places).

JONES BOYS

The first permanent member was George Riddle who joined Jones on harmony vocals and rhythm guitar in 1960. He stayed with Jones for four years and eventually got to sing and play on his records.
Originally they used local bands as they toured, in 1962 Jones bought his first tour bus and formed the first Jones Boys with Riddle.
The group started with Riddle (guitar, vocals), Billy Wayne (steel), Jerry Star (lead guitar, ex-Wanda Jackson), Gary Prawl (aka Gary Parker) on bass and Glen Davis on drums. (Davis with the Opry band in the 1990s).
Billy Wayne split and Hal Rugg (steel) replaced him.

Johnny Paycheck works with the group on and off, circa 1962?

In 1964 Jones has an uptempo hit with ‘The Race Is On’
Around this time Gary Adams and Johnny Paycheck are in the group. Johnny Paycheck switches to steel while Gary goes to guitar while Glen Davis (drums) is still with the group.

Circa 1965 Buddy Emmons works with the band. That same year Sonny Curtis (steel) joins the group alongside Glen Davis.
In 1966 fiddler Charlie Justice joins, while Jack Solomon (lead guitar) joins around this time.

In 1967 he opens the Possum Holler Nightclub in Nashville on Lower Broadway St. The Jones Boys played there fairly reguarly, especially as Jones was touring infrequently.

In 1968 guitarist Solomon marries Jones’ duet partner Melba Montgomery.

The 1968 into 1969 group featured James Hollie (bass, who’d worked with Wynn Stewart in Texas), Freddie Haws (drums), both from Dallas, Charlie ‘Grumpy’ Justice (fiddle), and Sonny Curtis (steel); both from Ohio.
As well as another Texan Charlie Carter (lead guitar).
With Tammy Wynette on tour with them, they added Patsy Sledd on harmony vocals, Tammy left due to her pregnancy later in 1969, while in early 1969 Jim Ebert (piano) was added.

The BLUE BOYS

Throught the early 1960s the group went through various bandmemers, including Jimmy Day, drummer James Kirkland, Henry Strzelecki (ex-Hawks), Mel Rogers, Bobby Dyson, and Roy Aldrige.

The Blue Boys as the 'Lump Lump Boys' their hillbilly gag group persona, perform at a live broadcast of KHAT radio, Phoenix, Arizona on May 18, 1961. At the time The Blue Boys consisted of James Kirkland (guitar), Mel Rogers (drums), and Dean Manuel (piano).

The core band settled with Leo Jackson rejoining as guitarist and bandleader, Dean Manuel (piano), Bud Logan (bass, vocals), and Jimmy Orr (drums).
On July 31, 1964 Reeves was piloting a single engine plane which crashed in heavy rain, killing him and band member Dean Manuel.

After the death of Reeves and Manuel, the rest of the group Leo Jackson, Bud Logan (bass, vocals), and Jimmy Orr (drums), go on to work as the Blue Boys with Bunky Keels on piano.
They recorded their own material and their debut album We Remember Jim Reeves (RCA/Victor 3331) 1965, Sounds Of Jim Reeves (RCA/Victor 3529) 1966, The Blue Boys In Person (RCA/Victor 3696) 1967, and Hit After Hit (RCA/Victor 3794) 1967.
