"The Best Years of Our Lives" was released in March 1975, reaching No. 5 in the UK. The second single from the album, "Mr. Raffles (Man, It Was Mean)", was also a success, reaching No. 13. The band embarked on a UK and European tour to promote the album. During the summer, the band recorded their fourth studio album "Timeless Flight". Around the same period Harley also produced Dutch singer Patricia Paay's album "Beam of Light", with the members of Cockney Rebel contributing to many of the tracks. On the album, Paay covered "Sebastian", as well as "Understand", which would also appear on "Timeless Flight". Later in the year, Harley and the band went on tour in the US as a support act to The Kinks. As the band had not achieved commercial success in the States, the compilation "A Closer Look" was released exclusively for the American market.
