Hall diagnosed with Lyme disease.

Hall & Oates are postponing up to 16 tour dates this summer because Darryl Hall has been diagnosed with Lyme disease.

Six dates have already been canceled or postponed on the tour, which launched last month in support of their latest album "Our Kind of Soul." Performances scheduled through the end of July are expected to be postponed.

A revised tour schedule will be announced soon. A June 26 Greek Theater show in Los Angeles has already been rescheduled at the same venue for Sept. 21. A June 28 stop at the Mountain Winery in Saratoga, Calif. has also been rescheduled at the same venue for Sept. 20.

Previously scheduled dates with Todd Rundgren, beginning Aug. 23 at the Bank of America Pavillion in Boston, will not be affected. Rungren/Hall & Oates dates run through the end of November.

Hall is expected to make a complete recovery.
