Boston star Tom Scholz is suing the band's former guitarist Barry Goudreau over allegations he is using the group's name to promote his solo career.
Goudreau played with the rockers for three years before quitting the line-up in 1979 following a legal battle with their manager.
According to editors at Tmz.com, Scholz offered the guitarist a severance package to leave the band, including 20 per cent of the royalties for the group's first two albums.
In exchange, Goudreau reportedly agreed to not use the Boston name, but Scholz has now taken legal action against his former bandmate over allegations he is boosting his solo career by using his connection to the stars.
Scholz also claims Goudreau is performing the group's songs at his shows.
