Norman’s Rare Guitars, a San Fernando Valley shop long favored by some famous musicians, may be on its last legs due to the coronavirus, according to media reports. TMZ.com, the Hollywood website, reported Monday that while the Tarzana shop is not in financial straits, its owner, Norman Harris, may have to keep the shop closed permanently after shuttering it in March. According to his daughter, Sarah Edwards, Harris, who has Type 1 diabetes, only comes into the shop two days a week for a few hours to pack and ship out internet orders and to record video for the store’s social media sites, the website said. Edwards is producer of a documentary on the shop and how it has inspired the careers of musicians and others in the entertainment industry. It is hoped the documentary, still in production, will raise awareness about the plight of the store at 18969 Ventura Blvd., TMZ reported. Guns N’ Roses guitarist Slash, the Goo Goo Dolls, Melissa Etheridge and actors Jeff Daniels and Jeff Garlin are among those appearing in the documentary, TMZ said, which is directed by Devin J. Dilmore, founder of 101 Exit Media LLC, in West Hills.
