In 1968, they released the up-tempo "Captain of Your Ship", co-written by Kenny Young. Although the song missed the U.S. national charts, it became their biggest ever hit when it made #13 in the UK Singles Chart, and the group toured there. The trio's backing group on this tour was Clouds. "Saturday Night Didn't Happen" and "Weather Forecast" were also issued as singles, but did not repeat the success of "Captain of Your Ship". Young said of this period: '"They were responsible for me moving to England. I accompanied them to Top of the Pops...attended the reception for their hit single "Captain of Your Ship", along with John Lennon and Ringo at the Revolution Club in London. I met half the Beatles at our own reception..."".
