Lead Vocals/Rhythm Guitar - Craig Mackenzie

Craig started his musical career relatively late. In 2012 Craig performed a solo cover act that entertained local pubs in the North Essex.

In September 2013, Craig joined a newly formed rock cover band Slippery Fret as lead vocalist which quickly received a positive reputation and gained gigs across North Essex and Suffolk. It was during this time that Craig met Colin (previous lead guitarist of Slippery Fret) and they embarked on a journey of writing their own material across the next year.

In June 2015, Craig decided to leave Slippery Fret to create the band of Jump Mother Crab which eventually would perform the tracks that he and Colin had written in addition to performing a wide genre of covers.

Craig's main influences are from the Britpop era, namely Oasis, whilst more recently Noel Gallagher, Kasabian and Stereophonics have all featured greatly on his playlist. Craig's Scottish roots also highlight why he has a keen interest in the Celtic/Country genre with Runrig being a personal favourite.

The youngest in the band, Craig brings a confident front man approach, and with his range of stage lighting and his harmony pedal tries to create that little something different on stage.


Lead Guitar - Colin Cripps

Colin has played in bands since he was 13 years old doing everything from covers to original material by both himself and others. He has played pop, blues, rock, soul, funk and folk, both electric and acoustic, and once headlined at Cambridge festival. This means of course that he has variously imagined himself as Keith Richards, Pete Townsend, Eric Clapton, Jimi Hendrix, Richard Thompson, Martin Carthy, Jimmy Page, Slash, Paul Weller, Nile Rogers, Buddy Guy, John Mayer and Joe Bonamassa: unfortunately, despite now being old father time, he never managed to look or play like any of them…  
Colin taught modern music in schools earlier in life and ran everything from big swing jazz bands to doo-wop vocal harmony groups. He once spent the school holidays bricking up the windows of a classroom to turn it into a music studio - pity he didn’t get permission first.
He has written and released a rock opera, "The Hermit", and a text book on modern music for schools: "Popular Music in the Twentieth Century".  Recently he has released two albums with singer/songwriter Bob Hughes and his own music is being used in a forthcoming horror film. He is currently enjoying his songwriting/arranging/producing partnership with Craig, who he hopes will make him a millionaire.

Colin is the musical driving force behind the band with his blistering guitar solos. One thing you can be sure on with Colin, he will never play the same solo twice!

Bass - Sean McNulty

After brief flirtations with trumpet and classical guitar, Sean started on drums in his first ' school ' band, then moved to bass guitar, when their bass player left. He has been gigging virtually non-stop since the age of 16, with ' originals ' and covers bands, and has performed as far afield as Holland, Cyprus and Dubai. Sean has enjoyed working with members of The Drifters, Dr Feelgood, Suzi Quatro band, as well as Jim Diamond, Kenny Lynch, and comedian Brian Conley. 

Sean's musical tastes range from James Taylor to Bruce Springsteen, The Beatles to Deep Purple, The Who to Level 42, Supertramp to Average White Band, The Sensational Alex Harvey Band to Earth, Wind & Fire, Hall & Oates to AC/DC.

Favourite bass players include John Entwistle, Jaco, McCartney, Phil Lynott, Pino Palladino, Mark King, Leland Sklaar, to name but a few.

"I love the direct, or subtle influence that different bass patterns can have upon a song, whether it be a driving rock beat, or a more sparse and melodic, or basic style, that allows space for vocals or guitar to express themselves. Also, the relationship between bass and drums working together, or playing off each other, is even more rewarding and enjoyable - I would love to play alongside Steve Ferrone, Steve Gadd, or Stewart Copeland for an evening - I wonder if they do 'Deps' ? " 

Sean joined the band in early 2018 and has already established himself in the band with his funky but driving bass playing, not to mention chipping in with some vocals!
