It’s throwback Friday!

You’ve got a whole lot of time periods covered on the tour that comes to the Mohegan Sun Arena on Friday. Here’s why: the line-up consists of New Kids on the Block, TLC and Nelly. Their biggest hits rolled out this way: NKOTB racked up their chart-topping singles in the late 1980s and ’90s, while TLC was all “Waterfalls” and “No Scrubs” in the 1990s and Nelly was hot (in herrrrre) in the early 2000s.

The headliners are New Kids On The Block, who reunited in 2007 and they have been, um, hangin’ tough ever since. The guys still put on a great show; they totally showed up the Backstreet Boys when they were on a double bill a few years back — take that, Boys.
