"Still in Love With You" is widely considered to be Thin Lizzy's greatest, most romantic ballad. Which is pretty ironic, considering it had little to zero songwriting input from the band's guiding force, Phil Lynott. In actuality, the bulk of the song was written by Irish guitarist Gary Moore, who had worked with Lynott during their formative years in the late '60s, then briefly joined Lizzy following the sudden departure of guitarist Eric Bell. This arrangement proved short-lived, however, and Moore soon moved on to a new solo project, never imagining that the forceful Lynott wouldn't be able to resist nicking his song and making it the centerpiece of Lizzy's surprisingly mellow breakthrough, Nightlife. Released in November 1974, the album added insult to injury by crediting "Still in Love With You" to Lynott alone, even though its final mix still featured the original solo recorded by Moore back in March (along with guest vocals from Frankie Miller). In concert, the ballad also became a nightly showcase for the band's future guitar players, Brian Robertson and John Sykes, both of whom turned in memorably impassioned performances of their own for 1978's legendary Live and Dangerous and 1983's farewell Life, respectively.
