Soul Brothers Six were an American rhythm and blues band formed in Rochester, New York, during the mid-1960s. They are best remembered for their song "Some Kind of Wonderful", which was later a big hit for Grand Funk Railroad.
The band was originally called the Soul Brothers Five and featured brothers Sam Armstrong, Charles Armstrong, Moses Armstrong, Harry Armstrong and Gene Armstrong. Shortly after the group's formation, vocalist John Ellison joined, prompting a name change. This lineup released two unsuccessful singles in 1965, "Stop Hurting Me" and "I Don't Want To Cry", before both Harry Armstrong and Gene Armstrong left the group, being replaced by Vonn Elle Benjamin and Lester Peleman.
It was this lineup that released the single "Don't Neglect Your Baby" before Sam Armstrong left the group to be replaced by Joe Johnson. They then signed a deal with Atlantic Records after being introduced to Jerry Wexler by a Philadelphia DJ and subsequently released "Some Kind of Wonderful" which reached #91. They followed with several more unimpressive singles before being dropped by Atlantic.
