Bluer than Blue:

Formed by guitarist Tony Skinner, drummer Andrew Kelly and vocalist/songwriter Harry Lang. Many lineupchanges followed when Tony Skinner left after a few years to concentrate on teaching.
Final lineup:
Harry Lang (vocals),
Pete Farrugia (guitar) (from Shout Sister Shout!)
David Gwilliam (guitar),
Ivan Thompson (sax),
Adrian Wallis (bass)
and Andrew Kelly (drums).

Appeared at all of the major UK Blues festivals, supported artists like Peter Green's Splinter Group, Sherman Robertson, Larry Garner and Angela Brown, and released the album "Through the Storm" (cover pictured above).

Split over the eternal question: weekend gigs or serious work?
Harry Lang and Pete Farrugia, wanting more work/albums/tours, formed Mo' Indigo, taking Ivan Thompson with them.
