* Good Morning America (7 am/ET ABC)
Water, water everywhere - that's where country fans can expect to hear "Water," the second single from Brad Paisley's new American Saturday Night CD, this summer. It shouldn't come as a surprise, seeing as how Paisley's coming off yet another No 1 hit with "Then" (his 10th No. 1 single in a row), not to mention two CMA awards last November and three CMT awards last month. And be very surprised if he doesn't play "Water" on this morning's GMA Central Park concert.
