The Young Lions managed to produce one minor hit with their song "Open Up Your Door". The composition was the first ever recorded using an African hair drum and a fuzz bass. It reached number one in Cleveland, Ohio; Detroit, Michigan; Elyria, Ohio; and Salt Lake City, Utah; number two in Seattle, Washington and Vancouver, British Columbia, Canada; number three in Tucson, Arizona; and the Top 10 in many other cities in the US and Canada. Nationally, it peaked at number 99 on the Billboard Hot 100 chart on September 24, 1966 and number 91 on the Record World Top 100 Pops chart on October 8, 1966. The corresponding Cash Box listing was at number 70 on October 22, 1966. The band made several television appearances including The Hy Lit Show and The Jerry Blavat Show out of Philadelphia, PA. They also appeared in the Detroit market on Robin Seymour's Swingin' Time show, out of Windsor, Ontario. A video of that appearance on Swingin' Time has survived to this day and can be found on line. And the band also made two appearances on the Upbeat TV show out of Cleveland, OH, hosted by Don Webster.
Their follow-up release, "Nasty", was chosen and released in late December 1966 and became a regional hit, but did not match the sales of their debut single. The Young Lions' final single, "You Can Make It" was released in February 1967 and received extensive radio play. However, the record company refused to distribute the single to the public, so "You Can Make It" failed to chart. The band sought to compose their own tracks, however they were no longer backed financially which led to their disbandment
