Kim Wilde had a slew of hits back in the 80s in both her native Britain and Stateside, but after the huge success of Kids In America and Keep Me Hanging On the singer appeared to fade into oblivion, and announced in 1998 that she was retiring from music and embarking on a new career as a landscape gardener.

But, now she's back….. In fine form!

The 52-year-old made the day - heck, probably even the year - for a bunch of sullen London commuters this week when she burst into an impromptu, and highly inebriated, performance of her 1981 smash hit.

With a pair of glittery reindeer ears perched atop her messy blonde hair, Wilde proved she still has The X Factor, belting out Kids In America accompanied by her brother Ricky Wilde on guitar and backing vocals.

And, that's not all!

Mindful of fully entertaining her captive audience, the singer graciously continued her performance, announcing to the crowd, "Everyone, it's Christmas time, and I'm going to sing you a Christmas song!" Then embarking on a somewhat shaky rendition of Rockin' Around the Christmas Tree.

Wilde's awesome "comeback performance" was captured on camera by subway passenger Katherine Eames
