The first trailer for the long-awaited sequel to This Is Spinal Tap has been released, showcasing the venerable rockers’ supposed last hurrah in a film called Spinal Tap II: The End Continues.

Spinal Tap II reunites Nigel Tufnel, David St Hubbins and Derek Smalls (played by Christopher Guest, Michael McKean and Harry Shearer) as they get together for a final concert, more than 40 years after the 1984 mockumentary that made their name. In between, Spinal Tap released the album Break Like the Wind in 1992, appeared on The Simpsons, played the Live Earth charity concert in 2007 and Glastonbury in 2009.

The trailer shows Marty DiBergi (director Rob Reiner’s totally on-point mickey-take of Martin Scorsese) is on hand to record the band’s doings, and megastars including Elton John, Questlove and Paul McCartney drop in to add their two-penn’orth to the Tap mythos. Filling in for An Evening with Stormy Daniels has to be the high point of anyone’s career, right?

• Spinal Tap II: The End Continues is out on 12 September in the US and UK, and on 25 September in Australia.
