JONATHAN KELLY - Kelly supported the Strawbs on their 1972 Grave New World tour, and his "Twice Round The Housees" album was a favourite with many folkies. This site run by Gerald Sables has lots of info about the elusive Kelly, who sadly died on 1 May 2020.
ROBERT KIRBY - Robert both arranged for and played with the Strawbs - the brass arrangement on "Heavy Disguise" and the orchestral work on "Down By The Sea", and some work on Two Weeks Last Summer. Better known outside Strawbs circles for his work with Nick Drake. The wiki article has a fascinating discography.
LED ZEPPELIN - archetypal heavy rockers, Strawbs and Led Zep struck up a friendship during the Strawbs' 1972 residency at the Troubadour in LA; some wild hotel room parties ensued, I'm told, complete with all the usual atrocities. Sandy Denny sang on Led Zep's "The Battle of Evermore", and of course John Paul Jones played bass on the Strawbs' first A&M album.
GERRY LOCKRAN - another stalwart from the old folk club days, Gerry was a regular visitor to the White Bear, the Half Moon in Putney and many of the other London-based clubs which were the Strawberry Hill Boys stamping ground in the 60s.
JUAN MARTIN - Martin, a celebrated flamnco guitarist, collaborated with members of Strawbs in some sessions arranged by Humphrey Walwyn in the early 80s, which were featured on A Taste Of Strawbs. Dave Cousins performed a fantastic version of "TheShepherd's Song" with him at the 2005 Christmas Party.
KATE AND ANNA McGARRGLE - Canadian duo, played at July Wakes Festival in Chrley, Lancashire, 1976, as did Dave Cousins in a then-rare solo spot. Sadly, Kate McGarrigle died on 18 January 2010 following a three-and-a-half year battle with cancer.
RALPH McTELL - a hardy perennial of the folk scene since the 60s, McTell penned the folk standard "Streets Of London". He also played alongside Cousins on Mary Hopkin's Earth Song Ocean Song album. Rick Wakeman played piano on his album You Well Meaning Brought Me Here
THE MELLOTRON - a crucial part of the classic Strawbs sound, the Mellotron was arguably the first (and possibly the most temperamental) sampler, using banks of tapes, one tape for each note. Wakeman was an early adopter (as were, according to Wikipedia, Princess Margaret, Peter Sellers, King Hussein of Jordan and Scientology founder L. Ron Hubbard). Those nice Streetly people loaned mellotrons for the Chiswick show. The software mellotron from G-Media even reproduces the 8 second tape length and a virtual coffee stain on the cream coloured instrument fascia - nice retro!
EDDIE MONEY - his 1983 album No Control (which made number 20 in te US charts) includes a cover of the Dave Lambert song "Take A Little Bit" from Dave's solo album Framed, credited to Lambert/Proffer/Money - he appears to have rewritten some of the lyrics. It may also have been released as a single. Still touring and recording with a new album in 2007.
NOEL MURPHY - one of the stalwarts of the late 60s folk scene, Ron Chesterman went to join Noel (along with a guy called Shaggis, aka Davey Johnstone - better known in later years as Elton John's guitarist) in a band called Draught Porridge.
