It would be tempting to call Kevin Armstrong the ultimate ‘nearly man’ of 1980s pop – he nearly joined a post-Johnny-Marr Smiths, was nearly a founder member of David Bowie’s Tin Machine, nearly joined Level 42 Mark II, and nearly became Paul McCartney’s right-hand man during the ex-Beatle’s late-decade renaissance.

But that would be unfair on the guitarist; as well as stellar work with Bowie (Live Aid, ‘Absolute Beginners’, ‘Dancing In The Streets’) and Iggy Pop (Blah-Blah-Blah, countless world tours), he has also contributed to classic albums by Prefab Sprout, Thomas Dolby and Morrissey and performed live with Roy Orbison, Sinead O’Connor, Grace Jones, Propaganda and PiL.

This entertaining Pizza Express show was half wonderfully-indiscreet spoken-word memoir and half gig. Decked out in all-black rock-star garb, Armstrong described his initiation into the music world via an obsession with Zappa’s ‘Black Napkins’ and postal-order guitar handbooks, and lamented the current pop scene as ‘just another part of consumer culture’.

He spoke of one life-changing morning in early 1985 when he received the call from legendary EMI A&R man Hugh Stanley-Clarke: an invitation to Abbey Road to record with ‘Mr X’.

Arriving at the famous address, Armstrong was shown upstairs to a tiny demo studio (not the big Beatles-frequenting Studio 1 downstairs) to find a bunch of session players and a smiling, suited Bowie holding an omnichord and uttering the totally superfluous ‘Hi, I’m David!’.

Bowie then proceeded to teach the band a song called ‘That’s Motivation’ (from the ‘Absolute Beginners’ soundtrack) two bars at a time – and they then recorded it that way too.

A few days later, Bowie summoned Armstrong to Westside Studios near Ladbroke Grove for the ‘Absolute Beginners’ and ‘Dancing In The Street’ recordings (the former with vocals by Armstrong’s sister, then working behind the till at Dorothy Perkins, responding to Bowie’s request for a ‘shopgirl’ to sing duet with him!).

The latter session was of course graced by an absurdly perky Mick Jagger. Apparently Bowie and Jagger spent most of the vocal sessions shouting ‘Let’s ring Maureen!’, their nickname for Elton John.

Armstrong then told great tales of Live Aid, mainly highlighting Bowie’s incredible generosity: fluffing the names of backing vocalists Helena Springs and Tessa Niles during his onstage band introductions (no other solo artist introduced his/her band on the day), according to Armstrong he immediately apologised profusely to the singers as soon as they were offstage.

There were further funny tales of Gil Evans, Iggy and McCartney (who apparently once smoked some unbelievably strong grass with Armstrong, said ‘That’s you stoned!’ to the erstwhile guitarist, then promptly disappeared) and an exceptionally eccentric Grace Jones who allegedly took a distinct liking to Armstrong at a party, taking him by the hand and leading him away for some sexual shenanigans.

Who should intervene but Bowie, grabbing Armstrong’s other hand and whispering in the guitarist’s ear: ‘No you don’t. She’ll have you for breakfast, sunshine…’

In the second half, Armstrong was joined by Iggy bandmates Ben Ellis on bass and Matt Hector on drums to perform songs that he’d played live with all the aforementioned stars.

Efficiently sung and superbly played, it was nevertheless a somewhat humourless set of music that only served to emphasise the difference between a perennial sessionman and born headliner.

But this was still a hugely enjoyable evening, foregrounding a time when music really was transformative. We await Armstrong’s forthcoming memoir with great anticipation.
