Gradually, as the key members will float away and leave the ship, the sound (which had a distinct west coast touch) shifted more and more towards typical late 70's AOR with a slight country rock touch.
The group will end its career in the early 80's in the general indifference after a string of unremarkable (from our point of view) string of albums. The band went on to become Headpins with a huge ard rock sound.
