Strawberry Switchblade were a Scottish female new wave duo formed in Glasgow in 1981 by Jill Bryson and Rose McDowall, best known for their song "Since Yesterday" from 1985, and their flamboyant clothing with bows and polka-dots. Rose McDowall and Jill Bryson were part of the bohemian art scene who adored the New York Dolls and who followed Scottish punk band Nu-Sonics (aka Orange Juice) during their career, with McDowall playing and recording with Paisley punk band The Poems.

Bryson studied for four years at the Glasgow School of Art where she achieved a BA honours degree in mixed media.

As friends, McDowall and Bryson socialised in Glasgow pubs, catching many local bands at the time. One of these bands was Orange Juice, fronted by Edwyn Collins. Members of New Pop and Orange Juice had recorded a live version of "Felicity" as a flexi-disc and intended to release it. A fanzine, to be titled Strawberry Switchblade after a James Kirk song, was planned to promote the flexi-disc but never materialised. The "Felicity" flexi-disc was eventually released in conjunction with the debut Orange Juice single, "Falling and Laughing". McDowall was later given the name by James Kirk.

The bands very first incarnation, an all-female 4 piece, recorded one demo at Glasgow’s Hellfire Club and played a handful of gigs. Friends Janice Goodlett and Carole McGowan completed the line up on bass and drums respectively.

Strawberry Switchblade played at a John Peel gig in Scotland, and he invited them to record a session for his BBC Radio 1 show in October 1982.They also recorded a session for David Jensen's Radio 1 show three days later. On both sessions the band were augmented by James Kirk from Orange Juice on bass and Shahid Sarwar from The Recognitions on drums
