Concert notice: Go-Go's and Rihanna ruin my summer by cancelling their Dallas shows

Just a quick note that if you haven’t heard, The Go-Go’s have canceled the remainder of their tour. Jane Weidlin injured herself in a hiking trip and has to have surgery on her ACL. Recovery looks to be about a year. Thus, no ’80s flashback at the Granada July 26.
The Rihanna/Ke$ha show at Superpages.com Center has also been nixed from its July 24 date. RihannaDaily.com says they don’t know the story, but “it’s not because the tour isn’t selling! Don’t believe gossip sites who doesn’t support her and wants her to fail.” Although, there seems to be a whole lot of buzz that her U.S. shows weren’t selling as much as expected. There is also speculation that her Tucson show was canceled as a protest to the new immigration laws.
Either way, scratch these off your concert calendar.
