Scott Weiland gave a less than stellar performance of the Stone Temple Pilots’ 1994 hit “Vasoline” during his new band The Wildabouts’ show on Tuesday, causing concern among fans.

“Alright, this is a new song. We just worked it out today,” the 47-year-old rocker told the crowd before launching into a monotone and lackluster version of the more than 20-year-old tune.

A rep for Weiland told TMZ that drugs were not a factor in the singer’s performance on Tuesday, but admits it wasn’t his best vocal, explaining that it was a “perfect storm” of Weiland being tired and having a few drinks before the gig.

Weiland has struggled with substance abuse issues for years, and as Diffuser points out, he’s had a rough couple of months with a case of mistaken identity that lead to false reports of him being arrested, as well as the death of his Wildabouts bandmate Jeremy Brown in March.
