AceShowbiz - Rockers Bon Jovi are raking in the cash on their current tour after grossing $52.8 million in the first half of the year to top a poll for the most profitable North American roadshows. The "Livin' on a Prayer" hitmakers have been delighting fans across the U.S. and Canada with "The Circle" trek, selling out dates.

The band played 38 shows in 28 markets in the first six months of 2010, selling more than half a million tickets to earn them the top spot on Pollstar's Top 100 North American Tours list. James Taylor and Carole King's joint concerts have pulled in $41 million to place them in second, while country sensation Taylor Swift is third with tour profits of $34.2 million.

Sir Paul McCartney's legendary status has garnered him fourth place after playing just seven gigs in five markets, grossing $31.6 million, and country trio George Strait, Reba McEntire and Lee Ann Womack round out the top five with ticket sales of $29.8 million.

The half-year poll comes just days after artists such as the Jonas Brothers, Rihanna and the stars of "American Idol" were forced to scrap concerts due to poor ticket sales.
