U2's tour continued in Cologne on Tuesday night and the band were said to be "in fine form" after they were forced to cancel Saturday's Berlin show when Bono lost his voice.
The Berlin show was dramatically cut short after a few songs when the front man decided he could no longer continue.
However, Bono assured fans that he would be "back to full voice for the rest of the tour".
A post on the Irish rockers' website confirmed that the tour is now back on track.
"The band were in fine form in Cologne tonight, the tour right back on track after Saturday's cancelled show in Berlin."
Meanwhile, footage from the Cologne gig posted on the band's official Twitter page showed Bono performing with his usual vigour along with the band in front of a packed crowd.
In a message posted on U2's website on Sunday, Bono assured fans he would be back in form for the rest of the tour.
"I've seen a great doctor and with his care I'll be back to full voice for the rest of the tour. So happy and relieved that anything serious has been ruled out", the statement read.
"My relief is tempered by the knowledge that the Berlin audience were so inconvenienced. There was an amazing atmosphere in the house, it was going to be one of those unforgettable nights but not for this reason… We can't wait to get back there on November 13."
U2 are set to play two nights in Belfast and four in Dublin later this year as part of their Experience + Innocence tour.
