No Smoke Without Fire
No Smoke Without Fire is the ninth studio album by rock band Wishbone Ash. It is the first album since 1972's Argus to be produced by Derek Lawrence. It is also the heaviest Wishbone Ash album in years, featuring rockers like the hit single "You See Red" and the multi-part progressive rock epic "The Way of the World." Many fans considered this to be a true return to form after their flirting with an "American" sound on their previous trio of albums.
After a 1978 tour to support the album, Wishbone Ash would take a one-year hiatus during 1979 before regrouping for songwriting sessions at the end of the year.
