In 1981 Johnson and Burch left the band, claiming they were tired of touring. Bush and Cowan continued the group, replacing them with virtuoso banjoist Béla Fleck and guitarist Pat Flynn. These two moved the band to new musical heights. Fleck's compositions such as "Metric Lips", "Seven by Seven" and "Big Foot" were very well received as were Pat Flynn's "Do What You Gotta Do", "Lonely Rider" and "On The Boulevard". Pat Flynn also brought strong lead and harmony vocals to the group as well as a distinctive guitar style.
