Did dusty sringfield join Motown

No, Dusty Springfield did not officially join Motown. While she was associated with the Motown sound and had a strong influence from the label's music, particularly in the 1960s, she remained with her own record label, Philips Records, and later signed with Atlantic Records. Her iconic songs, such as "Son of a Preacher Man," often reflected the soul influences typical of Motown, but she was never a part of the Motown roster.
