Willie Nelson's health condition worries fans after the onstage incident in Charlotte

Willie Nelson disappointed many fans when he failed to perform at a festival this past Saturday. He got onstage and seemed to be setting up to play and then he just left.

Before leaving, he set his guitar back down and threw his hat to the crowd according to a video posted on YouTube. It appears as though an illness prevented the singer from performing.

Willie Nelson, 85, was at Charlotte's PNC Music Pavilion on Saturday night to headline his Outlaw Music Festival. Fans were left confused, angry, worried and disappointed when he didn’t perform.

Live Nation Carolina issued a press release on Saturday night explaining that the singer hadn’t performed due to an illness. TMZ reported that the star had a stomach bug but was now well enough that he would perform Sunday night in Washington D.C.

A YouTube user named Michael Keim posted a video on Saturday night that showed Nelson shuffling slowly onto the stage, picking up a guitar, and then setting the guitar back down. He then suddenly whipped his cowboy hat into the crowd and shuffled back off-stage.

‘Due to illness, Willie Nelson was unable to play tonight at the Outlaw Music Festival at PNC Music Pavilion Charlotte. Fans are asked to please hold on to their tickets until the new date is announced.’

Keim's video noted that the singer came out and walked off twice. A number of concertgoers reported on Twitter that they then stood around for an hour.

Ultimately, they were told that Nelson would not be coming back and that the show was over. This isn’t the first time this year that the country singer has canceled shows.

Wide Open Country reported that he’d also canceled multiple concerts in February due to the flu. However, in that instant, fans in those cities were made aware well in advance.

The festival has been facing major blows this year. In April, Elvis Costello withdrew due to "a non-life-threatening surgical procedure."

Two weeks ago, Brandi Carlile pulled out because of unexpected family obligations overseas. On Saturday, fans only heard sets from alt-country innovator Sturgill Simpson, and Americana string band Old Crow Medicine Show.

Add-on performers Wild Feathers and Mitchell Lee were also on hand.
