Scott Weiland is rejoining Velvet Revolver, but only for one night and one show!

According to Blabbermouth, the former VR lead singer will perform with his ex mates for a good cause – the ‘Love You Madly: A Concert for John O’Brien’ benefit show, which is set to take place Thursday, Jan. 12, at the House of Blues in West Hollywood, Calif. In addition, Rage Against the Machine guitarist Tom Morello will appear on the bill along with Sheryl Crow, Maroon 5′s Adam Levine and others.

Weiland split from Velvet Revolver four years ago amid much acrimony. The band is still looking for his replacement, with a report that they are currently auditioning Ours singer Jimmy Gnecco.

Despite the nasty breakup, Weiland and the boys eventually patched things up on a personal level and they are on decent terms. Weiland even mused to Classic Rock magazine, “Who knows, maybe we’ll do some shows some time,” earlier this year. Looks like he wasn’t kidding.

The ‘Love You Madly’ show will pay tribute to ASCAP film composer John O’Brien, who was found dead at 45 in a Chicago hotel room in August. O’Brien worked on films like ‘Iron Man,’ ‘Pineapple Express’ and more. He was a special enough of a guy that a show in his honor is able to lure Weiland back in the Velvet Revolver fold, if only for an evening.

If you are gonna be in L.A. on Jan. 12, nab your tickets now. This is sure to be a “can’t be missed” event.
