I assume you have seen the youtube video which quotes
"(Rainbo 1001) Presented here is the A-side of a rare and highly desired slab of vinyl sought out by collectors of obscure 1960's Los Angeles Soul. Featuring the voice of sixteen year old Phyllis Brown, 'Why' was also composed by the young and soulful artist. Miss Brown was provided with quite a musical education growing up as her father was the founder of Rainbo Records which was housed within the Rainbo pressing plant on North Las Palmas Boulevard in Hollywood. Commencing in 1939, not only 45, 33 and 78 r.p.m. discs were manufactured at the Rainbo pressing facility but also records that were inside of toy dolls, flexi-discs and records on the back of cardboard cereal boxes were made there. By the time Phyllis was a young teen, crates of freshly pressed recordings, most notably, fine R&B specimens were at her fingertips begging to be listened to and absorbed which is exactly what she did. In 1966, Phyllis was booked at a session at Hollywood's Gold Star Recording Studios where two tracks, 'Why' and the Cliff Chambers dancer, 'Oh Baby!' were cut. In a musical style similar to that of the work of Gene Page, Fred Darian and Raul Abeyta, oddly no arranger credit was given on the label but whoever it was, they along with an ensemble of L.A.'s 'Wrecking Crew' successfully created a double-sided masterpiece that showcased the soulful voice of Phyllis Brown surrounded by the magical reverberation of the Gold Star echo chamber. Pressed in a miniscule run, both yellow and pink colored labels were pasted on 45's cranked out on the Rainbo label. The following year, Phyllis along with three other girls formed the group, The Babies and issued a couple of slick L.A. Pop singles on Dunhill that are highly recommended and worth seeking out. Phyllis continued to have a lucrative career recording demos for other songwriters as well as composing and making music as a solo artist and also with Sunny Threatt. In 2018 after a thirty-five year gap in making music, Phyllis continued to share her gift by recording an albums worth of material entitled, 'Songs I Haven't Forgotten'."
