And Will Young, a double Brit Award winner with eight million album sales since winning the original Pop Idol contest, takes centre stage on Friday, July 16.
A full supporting bill is to be confirmed for each date.
Will Young said: "I am very excited about the summer outdoor shows, it's been a long time since I have done a run of big outdoor summer concerts, not counting the festivals, and I get to play new venues in new counties.
"I am particularly looking forward to seeing the banners that appear in the crowd!"
James Morrison said: "I am excited to be invited to perform the first ever concert at Welford Road and I'm looking forward to what, I'm sure, will be a fantastic night for all!"
