At the end of 1967, fame was taking its toll and the group were at odds with each other. At the start of 1968, the Gibbs were vying for influence in determining the musical direction of the group, creating tension in the studio and on stage. Also in 1968, to promote "Horizontal" the group made their first appearance on U.S. television on "The Smothers Brothers Show" as well as "The Ed Sullivan Show". The group later filmed a TV special "Frankie Howerd Meets the Bee Gees" with Frankie Howerd. His 1968 composition "Only One Woman" (UK No. 5) was the Marbles' most successful single up to date. The Bee Gees were invited by Hollywood manager Lee Hazlewood at his party alongside the members of The Monkees and Honey Ltd.. The photos from that event were leaked, and two of the pictures showing Gibb was talking to actress Angela Cartwright, and the other, is Gibb who was shown playing guitar and the members of Honey Ltd. sing along.
