Former Beatles singer Paul McCartney has canceled the rest of his highly anticipated "Out There" Japan tour because of severe illness.

Reuters reported the legendary singer fell ill last week following his arrival to Japan. Since then, doctors have ordered him to take "complete rest" to heal his worsening viral infection.

McCartney's last Japan tour took place in November of 2013.

"I was really looking forward to playing in Japan again after we had such an amazing time here in November," McCartney said in an official statement, adding that his tour cancellation was "hugely disappointing."

The official statement also contained a thank you note from Paul McCartney to his friends that read, "I'd like to thank my Japanese fans for their love, messages of support and understanding."

Had McCartney continued on with his tour, he would have been able to perform at Nippon Budokan Hall, the venue that he and the rest of the Beatles performed during their first Japan tour in 1996.

Fans who had hopes to see McCartney perform live in Japan once again will be refunded their money.

According to ABC news, The most expensive tickets cost 100,000 yen ($1,000) each. These pricey tickets were purchased by some fans who traveled from out of town for the concerts.

ABC also noted that the Japanese are among the world's most avid followers of Western pop music.

One particular Beatles fan who was excited to be seeing Paul McCartney is 52-year-old Yohei Hashimoto. Hashimoto told ABC News that he traveled from western Japan for multiple concerts that were canceled.

He added, "Well, what can I do about it? I would rather wish for Paul McCartney to get better sooner and come back to Japan again."

Well said, Yohei!

We wish Paul McCartney a speedy recovery. Details on his viral illness and recovery process have yet to be released.
