The current lineup of Warrant paid tribute to their recently deceased former lead singer Jani Lane by dedicating the song 'Heaven' to him at their concert last night (Aug. 12) in Grand Forks, N.D.

Lane parted ways with the popular late '80s and early '90s hair-metal band for the third and final time in 2008. He wrote nearly all of Warrant's most popular songs, including 'Heaven' -- see our 10 Best Warrant Songs list -- but struggled with alcohol abuse much of his life, and was found dead in a hotel room Thursday (Aug. 11).

An early autopsy was inconclusive, but authorities reportedly suspect an accidental overdose as the cause of Lane's demise. Before the evening's show, founding Warrant guitarist Erik Turner declared it "a very sad day for rock and roll," and stated, "We never thought that when the song 'Heaven' was written we would be playing it some day in the memory of Jani's untimely death."

But that's exactly what they did later that night, with current lead singer Robert Mason eulogizing Lane on stage by saying, "The guy was loved and he wrote some amazing songs. Truth be told, I love singing them, I've always said that. If we do this one, can we dedicate this entire show to his memory? Let's all do this together...can we have cigarette lighters and cellphones, can we all bond together?"
