For a half-hour before the start of Tim Rushton’s “Love Songs” Saturday at the Tsai Performance Center, the 12 dancers from Danish Dance Theatre could be seen on stage warming up, stretching arms and legs, showing off their flexibility. They looked good. Unfortunately, when the actual performance started, it turned out to be just more of the same.

Danish Dance Theatre explains the idea behind the 70-minute “Love Songs,” which premiered in 2011, as “the individual’s lifelong journey to find love,” set to “cherished jazz classics from the good old days.” Rushton, who is the company’s artistic director and choreographer, chose nine songs, among them “Come Rain or Come Shine,” “All of Me,” and “My Funny Valentine.” His recorded versions, however, were performed not by artists from the good old days but by contemporary Danish-based singer Caroline Henderson, whose sweet but pallid voice offers more style than substance.
