The comedy rock duo have come along way with their three albums, TV series and movie – since they formed back in 1994.

Now as a fourth album and animated series are confirmed for 2018, Tenacious D’s Kyle Gass has had a chance to reflect on the “disastrous” The Pick of Destiny movie and revealed what he thinks the real Greatest Song in the World from Tribute is.

Express.co.uk caught up with the 57-year-old musician and actor at Ramblin’ Man Fair, where he was performing with Kyle Gass Band, a spin-off of Tenacious D.

Fans will remember Tenacious D in The Pick of Destiny flopped big time, making just $8.2 million (£6.2 million) in the US and debuting at No 11 on its opening weekend.
