Hiseman and Clarke had played in Colosseum together
and formed TEMPEST in the beginning of 1973.
For the band's first, eponymous album
(originally called Jon Hiseman's Tempest),
the line up was completed by Allan Holdsworth on guitar
and Paul Williams on vocals and keyboards.
Later in Tempest's brief history, they were joined
by Ollie Halsall, who had begun playing guitar with
progressive rock band Timebox.
With two guitarists, the group played a number
of shows including a June 1973 show at
Golders Green Hippodrome.
By the time a second album was recorded, 1974's
"Living in Fear", Tempest was down to a trio,
consisting of Hiseman, Clarke, and Halsall;
reportedly Holdsworth didn't want to play alongside
a second guitarist.
The band broke up soon after. after.
After leaving Jethro Tull, Glen Cornick played as
a session musician for
Leigh Stephens in his 1971 album And a Cast of Thousands.
In the same year, he formed Wild Turkey, initially with:
Graham Williams (guitar), Alan 'Tweke' Lewis (guitar),
John "Pugwash" Weathers (ex-Pete Brown & Piblokto!)
(drums) and Gary Pickford-Hopkins (ex-Eyes of Blue)
on vocals; but Weathers and Williams left to join
Graham Bond's Magick before Wild Turkey recorded
any material - soon after, Weathers joined
the progressive rock band Gentle Giant.
They were replaced by Jon Blackmore (guitar and vocals)
and Jeff Jones (ex-Man) (drums) who joined Cornick,
Tweke and Pickford-Hopkins to record Wild Turkey's first
album Battle Hymn - which only reached number 193
in The Billboard 200.
