Following the success of "Grapevine", the group worked frequently with Norman Whitfield. Whitfield produced them the hits, "The End of Our Road", "It Should've Been Me", "Friendship Train", "Nitty Gritty" and "You Need Love Like I Do (Don't You)". They also recorded Ashford & Simpson's "Didn't You Know (You'd Have To Cry Sometime)" in 1969. They scored their second million-selling Motown single with the ballad "If I Were Your Woman" in 1970. Another ballad, the self-composed "I Don't Want to Do Wrong", became another million-selling single. Both singles were featured on their first number one album, also titled If I Were Your Woman. In late 1971, they released a soulful version of Kris Kristofferson's "Help Me Make It Through the Night", which became an international hit. The group released the Jim Weatherly ballad, "Neither One of Us (Wants to Be the First to Say Goodbye)", in December 1972, the single would become their last single released while still with the label. As the single was charting, the group tried to negotiate a better contract with Motown. Negotiations fell through weeks later and, in February 1973, the group left Motown and signed with Buddah Records. "Neither One of Us" became their biggest selling single at Motown, reaching number two on the Billboard Hot 100 and winning the group a Grammy for Best Pop Performance by a Duo or Group with Vocals.
