The fans seem to love him:

Meanwhile, Niall Horan said it was "nice" of his former bandmate to dedicate a song to his hometown during his performance at Slane Castle.

"I knew he was playing Slane so that’s obviously a very special place to us," Horan said, speaking to ITN at Capital’s Summertime ball.

“I hope it went well. He gave Mullingar a shout? That’s nice. It’s not far from Mullingar where he played."

Niall, 29, released his third solo album last week.
