I first saw them play Kiel Auditorium, St.Louis, Missouri in
January of 1977. The Michael Stanley Band opened the show and
Leslie West (as a solo artist) followed before Heep headlined.
Obviously it was one of the earlier Lawton sets to be played in
the USA. I do remember they played both Sympathy and Firefly off
the then unreleased Firefly album along with The Wizard and
Sweet Lorraine amongst others.
