There are at least TWO musicians using the name "Glenn Jones." (1) Glenn Jones the acoustic-folk guitarist, who is both a solo folk artist and a member of the Boston-based band Cul de Sac. (2) Glenn Jones the R&B, soul singer from Jacksonville, Florida.
These are photos from concerts where Glenn Jones played, so they may be of other bands that played the concert as well.
