Daryl Hall & John Oates join forces with Michael McDonald [ tickets ] this summer for a co-headlining run dubbed the Rock 'n Soul 2004 Revue.

The outing--which features Average White Band in the opening slot--kicks off in late June, and dates for the first leg are set through mid-July. A second leg, for which dates have not yet been announced, will run from mid-August through mid-September, according to organizers.

Registered users of the tour's online-ticketing service will have access to a ticket pre-sale that begins on Tuesday (3/23), according to McDonald's website. On-sale dates for the general public were not available at press time.

McDonald is supporting last June's "Motown," which features the baritone-voiced singer-keyboardist's interpretations of Motown classics such as "I Heard It Through the Grapevine," "Sign, Sealed, Delivered I'm Yours," "How Sweet It Is (To Be Loved by You)" and "Ain't No Mountain High Enough." The album recently went platinum, signifying U.S. shipment of 1,000,000 copies.

Hall & Oates [ tickets ] are backing last year's "Do It for Love," which is the duo's first new studio effort since 1997's "Marigold Sky." The set features the singles "Forever for You," "Man on a Mission" and the album's title track.

The pair is currently at work on a new album that is expected to surface sometime this fall, according to the Hall & Oates website.
