Steely Dan's former singer David Palmer is suing the group over a royalties spat.

Palmer claims his work on the band's early tracks helped to give the act its signature sound, but insists he has been paid just over $8,000 (£5,000) in royalties from radio play.

The singer, who quit the group in 1973, insists he is owed more and is suing for unspecified damages, according to Tmz.com.
