In April 1978, James released his debut solo album, "Come Get It!", which included the Stone City Band. The album launched the top 20 hit, "You and I", which became his first number-one R&B hit. The album also included the hit single, "Mary Jane". It eventually sold two million copies, launching James's musical career to stardom, and helping out Motown Records at a time when label fortunes had dwindled. In early 1979, James's second album, "Bustin' Out of L Seven", followed the previous album's success, eventually selling a million copies. A third album, "Fire It Up", was released in late 1979 going gold. Around that same period, James launched his first headlining tour, the Fire It Up Tour, and agreed to invite the then-upcoming artist, Prince, as well as singer Teena Marie, as his opening act. James had produced Marie's successful Motown debut album, "Wild and Peaceful" and was featured on the hit duet, "I'm a Sucker (For Your Love)". James was credited with naming Marie, "Lady Tee", on the song, a nickname that stuck with Marie for the rest of her career. The Fire It Up tour led to James developing a bitter rivalry with Prince, after he accused the musician of ripping off his act.
