In summer 1967, the Dells were on the low end of the hierarchy of the Chess Records roster, having returned to the label in 1966 after having hits with another Chicago-based label, VeeJay Records. Miller, now a Chess staff producer, picked the group to work with, amid much guffaws, after a staff meeting with Leonard Chess.
Their collaboration with Miller and arranger Stepney yielded a hit single, O-O, I Love You, which went to number 22 R&B in late 1967. Their career-making fast-selling album There Is was issued in March 1970. The title track was written by Miller and Raynard Miner. The single, There Is b/w the Motown-ish Show Me, peaked at number 11 R&B in early 1968. The hits continued with a majestic six-minute remake of Stay in My Corner (number one R&B for three weeks, number ten pop in summer 1968) and Always Together (number three R&B, fall 1968). Miller wrote both songs for the double-sided hit I Can't Do Enough b/w Hallways of My Mind in spring 1969. Other hits were the medley I Can Sing a Rainbow/Love Is Blue, which went to number five R&B in late spring 1969; Oh What a Night -- a respelled remake of their VeeJay hit -- that went to number one R&B in summer 1969; an up-tempo cover of Otis Redding's Sitting on the Dock of the Bay; Oh What a Day, which hit number ten R&B in early 1970; Open Up Your Heart, which hit number five R&B b/w a remake of the Coronets' Nadine in spring 1970; a cover of Lee Andrews and the Hearts' 1957 hit Long Lonely Nights; and The Glory of Love from early 1971.
In the fall of 1969, Leonard Chess, one of the group's biggest supporters, suffered a fatal heart attack. The following year, Bobby Miller left Chess for Motown and Charles Stepney took over the production duties for the Dells. ~ Ed Hogan, Rovi
