With a project title of BIG COCK the pairing of LYNCH MOB's Robert Mason and erstwhile KING KOBRA guitarist David Michael Phillips (a.k.a. David Henzerling) could only succeed in making an impact by announcing the "rebirth of American cock Rock". Mason also held a tradition fronting MAGNUM, ADRIAN DODZ and THE PACT. After a spell with SILENT WITNESS he went onto front CRY OF LOVE. Mason was fleetingly singer for RATT in 2000 and parallel to Big COCK would front up Troy Lucketta's ALIVE. On drums would be John Covington, an erstwhile partner of Henzerling's in the pre-ICON act THE SCHOOLBOYS and member of the GREG LEON INVASION. A formative 2001 BIG COCK line-up included former SURGICAL STEEL bassist Mark Lehman.

The BIG COCK album 'Year Of The Cock' made headlines in mid 2005. However, much of the material was in fact re-recorded from archive songs, including 'Mean Street Machine', which had already been laid down by THE SCHOOLBOYS, ICON and KING KOBRA. The song 'Cinammon' had been first recorded by TOMCATS.

BIG COCK, retaining a stable line-up, released a second album, simply titled 'Big Cock', in July 2006. The 2007 version of GREG LEON INVASION re-introduced original drummer John Covington. A third BIG COCK album, 'Motherload', arrived in February 2007.

The following year Covington temped on the live circuit for RHINO BUCKET.

David Michael Phillips sessioned for BANG TANGO for concerts in July 2009.Meantime, Robert Mason enrolled into the ranks of WARRANT. With BIG COCK on hiatus, David Michael Phillips forged 70s Rockers TUNNEL in union with ICON's Scott Hammons.
