Elton John was diagnosed with walking pneumonia - a less severe form of pneumonia - before his concert in Auckland, New Zealand. The singer attempted to brave his condition during the show, but had to conclude the set earlier than planned.

After cancelling the remainder of his Auckland concert, the "Rocket Man" singer offered a sincere apology on Twitter.
