The band is back together for a new round of music, chaos in 'Spinal Tap II: The End Continues'

HOLLYWOOD -- Four decades after "This Is Spinal Tap" hit theaters, the band is coming back together for one final concert and a sequel, "Spinal Tap II: The End Continues."

Marty DiBergi chronicled Spinal Tap back then as it embarked on a major tour that turned into a minor one! And now he's back to cover the band reuniting for one final concert in "Spinal Tap II: The End Continues."

"I'm just a lowly documentarian who's trying to capture the soul and the beauty of a band that I've admired for 50 years," said DiBergi.

The characters David St. Hubbins, Nigel Tufnel, and Derek Smalls reunite with DiBergi for a new mockumentary.

The film features some big-name cameos, including Elton John and Paul McCartney...all still performing in their 70s and 80s.

"Spinal Tap II: The End Continues" is in theaters now.
