Following Megadeth frontman Dave Mustaine's announcement Monday (June 17) that he was undergoing treatment for throat cancer, his bandmate, Megadeth co-founder and bassist David Ellefson, detailed the band's decision to cancel shows following the singer's diagnosis.

Vocalist and guitarist of the band Megadeth, Dave Mustaine, said in a Facebook post that he has been diagnosed with throat cancer.

Megadeth's Dave Mustaine apparently wishes he wrote the memorable riff in "The Pink Panther Theme," the 1963 jazz number behind the original Pink Panther film.
