The Ink Spots

The Ink Spots were a vocal group popular in the 1930s and 1940s that helped define the musical genre that led to rhythm and blues and rock and roll, and the subgenre doo-wop. They gained much acceptance in both the white community and black community largely due to the ballad style introduced to the group by lead singer Bill Kenny. They were inducted into the Rock & Roll hall of fame in 1999. Since The Ink Spots disbanded in 1954, there have been well over 100 vocal groups calling themselves "The Ink Spots" without any rights to the name or any original members in the group. These groups often have claimed to be "2nd generation" or "3rd generation" Ink Spots. Many such groups are still touring today.
