Sir Elton John was joined by Dua Lipa on her TV show titled An Evening with Dua Lipa.

Due to his ongoing health struggles and significant vision loss, Elton had to be guided on and off the stage by an assistant, according to MailOnline.

The show, which will air on December 8, features a memorable duet of their hit song Cold Heart.

Dua introduced Elton on stage, saying, “Give it up for a man who needs no introduction, Elton John.”

An audience member described the moment to the outlet, saying, “the chemistry between Elton and Dua was really sweet and joyous to see, they clearly have a lot of love for each other and to see that live was special.”

“He obviously wasn’t as active a stage presence as in years gone by, needing to sit down and be escorted onto the stage, but he sang as well as he ever has and filled the hall with emotion,” they revealed.

The concertgoer also added that it was “bittersweet to see him struggling a little, and I didn’t know the extent of his vision loss” however adding “it’s amazing he can still create such a fantastic environment in a venue of that calibre.”

“It was incredible to see Elton John live, we were ecstatic to see him and truly shocked that he had come,” another attendee shared.
