a piano and vocal version of the song, after which Collen, bassist Rick Savage and drummer Rick Allen added acoustic and electric guitars, bass guitar and drum parts in June 1993, creating the acoustic version that would be released as a single. Two unfinished songs from the Hysteria recording sessions, "Desert Song" and "Fractured Love", were completed exclusively for the album. The album also features several covers, namely Sweet's "Action" (which charted higher than the original in the UK) and Mick Ronson's "Only After Dark". The version of "Ride into the Sun" on the compilation is not the same as that which appeared on The Def Leppard E.P., but rather the 1987 re-recording. It differs slightly from the original B-side from the Hysteria era; the B-side featured a Rick Allen drum solo intro, whereas the version on Retro Active has a piano intro provided by Ian Hunter. Retro Active features a hidden (final) track: a piano/vocal version of "Miss You in a Heartbeat", which also features an alternate acoustic guitar solo by Collen. This is the first Def Leppard album to feature songs recorded with newly added guitarist Vivian Campbell.

The mirror itself forms the shape of the skull and the accessories on the dressing table form the nose, nostrils and teeth. It was inspired by Charles Allan Gilbert's most famous work, All Is Vanity (1892). An alternate version of the album cover exists, only released for promotional use. The only difference is the Def Leppard logo is represented in the most traditional style seen on Pyromania, Hysteria and Adrenalize. The band felt that, given Retro Actives sonically darker tone, that it would be best to shelve the bright colours of the logo. Reception In a 3.5 out of 5 review, Sputnikmusic wrote that while the compilation "cannot be rated super highly, it is extremely rare for a compilation album such as this to do so. With that in mind, this is indeed a pleasant surprise which will at
