The Longest Johns are periodically joined by guest artists on their livestreams (usually in streams titled "The Longest Johns and Friends"), greatly increasing the diversity of the music showcased and bringing new artists to fans of TLJ. The following artists have made appearances:

  • El Pony Pisador - Facebook - Bandcamp
    "El Pony Pisador, are a five-strong group from Barcelona, they play a mix of international music styles from traditional Irish tunes to Tuvan throat singing and yodelling." (Source) They headlined the Great Yarmouth Maritime Festival in 2017.
  • Rosie Calvert, from The Teacups - Facebook - Bandcamp Website
    "The Teacups show how old songs can be transformed by four voices and imaginative new arrangements. They started singing together at Newcastle University, which they left last year, and have already established a distinctive, fresh and impressively varied style." (The Guardian)
  • Sam Brookes - Facebook - Bandcamp - Website
    "With his keening tenor vibrato sailing effortlessly into the upper register, there’s something of Tim Buckley about Sam Brookes, especially when it’s set among starlight droplets of electric guitar on tracks such as 'Breaking Blue'."(The Independent)
  • (Briefly) Katie Sky - Facebook - Bandcamp - Youtube
    "After conquering YouTube with a series of hugely popular covers, Katie Sky was snapped up by Manchester’s Lab Records in 2011. Since then, Katie has gone on to win over a whole new set of fans with her original punchy pop sound" Source
  • Jimmy Aldridge and Sid Goldsmith - Facebook - Youtube - Website
    "Given that they grew up just five miles apart in Norfolk and later both did the rounds in the same Bristol folk music scene, you’d be forgiven for thinking that they were destined to join forces at some point, but the route to their current status has been more circuitous than you might imagine. Goldsmith spent years working in traditional horticulture, while Aldridge obtained a PhD and worked in Westminster as an environmental policy adviser. Their paths finally crossed eight years ago, and the rest is history." Source
  • Martin "Boohdot" - Shantykoor Blankenberge website - Dutch language
    The Longest Johns fan community's own resident punsmith, Martin (alias Boohdot), played host to Andy, Dave, JD and Robbie (absent Anna who had obligations with the Norfolk Broads) in Blankenberge, Belgium. Boohdot sported an impressive set of pipes all his own, showcasing his own singing talent by leading both [Pique La Baliene] and Bay of Suvla. Boohdot is a member of Shantykoor Blankenberge, a choir boasting more than 40 active members which specializes in shanties.
  • Natalie Holmes - Facebook - Youtube - Bandcamp - Website
    "Bristol-based singer/songwriter Natalie Holmes writes lilting, haunting and yet somehow invigorating pop, with honey-toned vocals and an incredible depth to every song." Source
