Frankie & The Spindles

They had started out on the Baltimore soul scene as two separate groups -- one was known as Frankie and the Spinners and the other, Little Ray and the Playboys. The groups eventually got together because one member had quit and another went to join the Marines. In 1968 the group started to record and had to change their name because of Motown group, the Spinners. Thus Frankie and the Spindles came to be.
The were still playing gigs as Frankie & the Spinners in late April 1968 but had their Roc-ker 45 on the US national soul chart by July, so I guess they had only changed their name when the 45 had escaped into the shops.
