I was more than Nirvana's 'sideman', says Grohl

Former Nirvana star Dave Grohl insists he was more than former bandmate Kurt Cobain's "sideman", maintaining his role was fundamental to the band's success.

The Foo Fighters frontman, 38, insists he and bassist Krist Novoselic played crucial roles in creating the 90s band's distinct sound and is tired of being overshadowed by late singer Cobain.
