Irish vocalist Daniel O'Donnell will embark on his largest North American tour to date, visiting approximately 3,000- to 5,000-capacity venues, beginning with four concerts at Ontario's Niagara Falls Memorial Arena from Dec. 3-7.

Those live performances will follow a month-long residency at the Tri-Lakes Center in Branson, Mo., which began Nov. 1 and runs through Dec. 1.

After a lengthy break, O'Donnell will resume the North American tour on May 8 at the ENMAX Center in Lethbridge, Alberta. From there he'll play nearly 20 concerts through June, visiting several markets for the first time, including Las Vegas, Cleveland, Portland, Maine, Moline, Ill., and Pasadena, Calif., among others.

The 2007/2008 North American tour may be his largest to date, but O'Donnell is no stranger to performing in the U.S. and Canada. "For the past five years or so, we have come to [North America] twice a year," O'Donnell tells "In May/June time, we tour various cities in the U.S. and Canada. Then in November, we spend at least three weeks in Branson, Mo., at the Tri Lakes Theatre."

"For me, touring is the most important part of my career," he continues. "When I started in this business, my main aim was to become a successful live artist."

Along with touring, O'Donnell has had a strong presence on television, primarily on PBS. The singer has already participated in seven PBS specials, with a new one slated to run in March 2008. "The recording, TV appearances and promotion are something that I do because they go hand-in-hand with the live shows," he observes.

As such, PBS has played a large role in raising awareness for his concerts and exposing fans to new music. "Prior to our shows being aired on PBS, the number of people coming to see us at the concerts in this part of the world was small," O'Donnell recalls. "After the first special aired, our shows started to sell out."

In August, O'Donnell released his latest album, "Can You Feel the Love," which entered the Top World Music Albums at No. 10. The set is the Irish singer's 25th title on that chart, which extends his lead for the most albums placed on World Music. All of four of those have reached the top 10.

In addition to concerts, album releases and TV specials, O'Donnell will release "Daniel O'Donnell's Ireland: Songs and Scenes from My Homeland," a new hardcover book due Feb. 19 via Virgin Books.
