In 2014, a definitive edition of the album was released by EMI, as a four CD+DVD box-set. On disc one, aside from the original album, the B-Side "Another Journey" is included, as well as early demo version of "Make Me Smile (Come Up And See Me)" and "The Best Years Of Our Lives" - both previously unreleased. The second and third discs consist of tracks performed live at the Hammersmith Odeon in London, on 14 April 1975. The fourth is a DVD, with footage of the same concert.
The song "It Wasn't Me" lyrically details mankind's tendency to blame their misdemeanors on their chosen god.
Allmusicjournalist, Donald A. Guarisco wrote "By his third album, Steve Harley had developed a strong grasp of how to combine his artistic ambitions with strongly crafted pop tunes that win the casual listener over to his artsy cause. The result was The Best Years of Our Lives, the most successful album of his mid-'70s heyday. All in all, it is a fine, slickly crafted album that will delight Steve Harley enthusiasts and will also appeal to fans of glam-oriented 1970s English rock."
In the Record & Popswap Mirror magazine of 8 April 1975, a review of the album noted "Forget No 1 singles; this will change everything. In nine songs, Harley wipes out his two-album apprenticeship with a stunning change of direction and commitment. Using the license of someone who knows he's on top, Harley continually swops style and musical approach to present a progressive collage of youth. It is a coming of age, a political and religious protest, a brilliant snap-book for a generation, a puzzle. In short, this third album demands attention. It is completely fulfilling, a monster unleashed."
