A few more cities have been added to Clay Aiken [ tickets ]'s summer tour, which will take the pop star and a full symphony orchestra to US cities from coast to coast through August.

The outing is set to launch with a bang July 4 in Frisco, TX, and cities added to the fold since last check include Newark, NJ; Knoxville, TN; and Fort Myers, FL. Confirmed dates are listed below.

The summer jaunt will finally give Aiken a chance to fully support his third studio album, "A Thousand Different Ways," which snagged the No. 2 spot on The Billboard 200 when it was released in September. The singer found himself in a somewhat awkward position when the record hit shelves, being that he'd already lined up holiday shows for the remainder of 2006, limiting his ability to promote the new set.

"A Thousand Different Ways" comprises 10 cover versions of love songs spanning the last three decades, plus four new tunes. Renditions of Harry Nilsson's "Without You," Elton John's "Sorry Seems to be the Hardest Word" and new single "A Thousand Days" are streaming at Aiken's MySpace page.

The set follows the Aiken's multi-platinum 2003 debut, "Measure of a Man," and 2004's platinum-selling "Merry Christmas with Love."

Aiken, who was the second-season runner-up on FOX-TV's "American Idol," has used his music career to further his humanitarian efforts. The former teacher created the Bubel/Aiken Foundation to promote and fund education and recreational programs for children with special needs, and he acts as a goodwill ambassador for UNICEF.

The performer also added "best-selling author" to his list of titles when he released his autobiography, "Learning to Sing: Hearing the Music in Your Life," in 2004.

Looking ahead, Aiken has been tapped as the exclusive musical guest for the "Capitol One Holiday Celebration on Ice," which will be taped Nov. 6 in Las Vegas and aired on NBC-TV Christmas Day.
