Video: KILLSWITCH ENGAGE Rejoined By Singer HOWARD JONES On Stage At Second London Concert

Former KILLSWITCH ENGAGE singer Howard Jones once again made an appearance during the band's concert Saturday night (August 11) at the O2 Arena in London, England, dueting with current KILLSWITCH frontman Jesse Leach on the group's classic song "The End Of Heartache". Fan-filmed video footage of the performance can be seen below. Jones previously joined KILLSWITCH ENGAGE on stage for the same song Friday night at the O2 Arena.

After Friday night's show, Leach wrote in an Instagram post: "Nothing but respect for my dude Howard. It was rad to share the stage with him tonight and hear him belt out 'End Of Heartache'! What a voice! If you haven't already, you need to check out his killer band @lightthetorchband huge sing along and heavy riffs with those soaring melodies from my man Howard! Really happy to finally become good friends and keep in touch with him after all of these years."

KILLSWITCH ENGAGE is currently touring Europe as the support act for IRON MAIDEN.

Leach appeared on KILLSWITCH's self-titled debut and sophomore album, "Alive Or Just Breathing", before exiting the band. Jones took over on vocals for "The End of Heartache", "As Daylight Dies" and the 2009 self-titled set before being dismissed from the group six years ago.

Jones is currently the frontman of LIGHT THE TORCH, which recently released its debut album, "Revival", after issuing two efforts under its previous name, DEVIL YOU KNOW.

Howard recently recorded a guest appearance on a new KILLSWITCH track, to be included on the band's next album. Leach revealed that he wrote the lyrics to the track several months ago "with Howard in mind and our connection through our similar mental illnesses." He explained: "I mean, now that I've hung with this guy a few times, it's 'crazy' (pun intended) how similar we are. We are brothers in metal, anxiety, hardcore music, love of medicinal marijuana and fighting depression.

"We may be very different-sounding voices, but, in truth, we are similar in many ways in our minds," he added.

Jesse went on to say that the song's lyrics are "about keeping hope in dark times and helping out those in need."

Leach, who has previously blamed his exit from KILLSWITCH in 2002 on his battle with depression, said that he planned "on using this song to help continue to raise awareness for mental health and suicide prevention. Both Howard and I have a very strong outspoken stance on the subject and I will use this to help with the cause," he said.
