Archer was also a member of British band Wild Horses, Stampede, Lautrec, Medicine Head and Rhode Island Red with Gary Leiderman on bass (ex-Talk Talk, Thin Lizzy), Manolo Antonana on drums and frontman/actor/writer Mike Dyer.

Stampede re-formed in 2009[2] in the wake of renewed interest and the CD re-issues of both The Official Bootleg and Hurricane Town via UK-based Rock Candy Records and Universal Music in Japan.

In 2011, Archer also began playing in the band X-UFO, alongside fellow former members of UFO, Danny Peyronel and Clive Edwards, with Rocky Newton (ex-McAuley Schenker Group) on bass.

In May 2016, Mark Stanway announced the reformation of Phil Lynott's Grand Slam together with Laurence Archer, Micky Barker, Neil Murray and Stefan Berggren.

In March 2019, Archer confirmed he was recording new material for Grandslam, with Mike Dyer, David Boyce, Benji Reid.
