BOLOGNA, Italy — Popular 1980s synth-pop duo the Eurythmics may have recently reunited, but former lovers Dave Stewart and Annie Lennox kept their distance from each other during a two-hour concert Monday at Palamalagutti.

"We could not be together, and we could not be apart," Lennox sang during "Seventeen Again," a song from Peace, the duo's first studio LP since 1989's We Too Are One. It's due Oct. 19.

When introducing that song, Lennox said, "This is the story of me and Dave."

Lennox, 44, and guitarist Stewart, 47, rarely exchanged glances or even stood near each other during a hits-heavy show that clearly pleased the crowd of 8,000.

Stewart played a series of glittering guitars while prowling the stage, which sported artificial trees and an enormous video screen. Lennox, in short red hair and black glasses, sang and talked to the audience.

The duo played only a few other songs from Peace, instead concentrating on their '80s hits, leaning especially heavily on songs from Be Yourself Tonight (1985). From that album, they played "There Must Be an Angel (Playing With My Heart)" (RealAudio excerpt of live version), an acoustic "Would I Lie to You?" and "Sisters Are Doin' It for Themselves" (RealAudio excerpt). Lennox sang the latter, originally a duet with soul queen Aretha Franklin, with backing vocalists Claudia Fontaine, Beverly Skeete and Faye Simpson.

The duo occasionally played alone, but most of the time were backed by Steve Lewinson on bass, Sam Flynn and Joel Campbell on keyboards, Chris Davis on saxophone and Pete Lewinson on drums.

"They're formally perfect, the songs are still great, but they look a little cold," concert-goer Dorina Gelmi, 29, said.

The 21 songs in the setlist included only a few from Peace, including the opening "I Want It All," the single "I Saved the World Today" and "Peace Is Just a Word," which showed up during the last encore set. The duo closed the show with their 1983 #1 pop hit "Sweet Dreams (Are Made of This)" (RealAudio excerpt of live version).

The Eurythmics gained worldwide success in the '80s as they evolved from a synth-pop duo to a soulful rock duo. They separated after We Too Are One, which drew tepid reviews.

Lennox launched a solo career with the double-platinum Diva (1992) — which was represented during the concert's first encore by "Why." Since the duo parted, Stewart has concentrated on writing movie scores and producing albums for other artists, including Tom Petty, Bob Dylan and Mick Jagger.

The Eurythmics' reunion tour — which began three weeks ago in Cologne, Germany, and included a performance Saturday at NetAid in London — supports humanitarian organizations Amnesty International and Greenpeace. It is scheduled to continue through Europe, Australia and the United States until the end of the year.
