Dave Grohl has found a curious side effect to the FOO FIGHTER's longevity - they've been going so long their fans have grown old.
The MONKEY WRENCH hitmakers have been making music for 11 years and have watched with interest how the crowds at their gigs have matured.
Grohl says, "We probably get more parents at our f**king shows than kids these days.
"We should have a special sticker on our records: 'Caution. Children's Advisory. Your parents will dig this. Do not buy.'"
