The Ice Bucket Challenge is all the rage these days.

Aside from providing amusement from seeing one of your friends or perhaps a celebrity being doused in ice water, the purpose of the stunt is to promote awareness and raise money for ALS research.

Now the challenge might actually produce a welcome side effect - helping to restore the working relationship between two of rock's biggest icons - Jon Bon Jovi and Richie Sambora.

Jon recently took the Ice Bucket Challenge, as you can see in the video below. The participant in the challenge is called to nominate three new participants, and Jon decided to challenge Bon Jovi bandmates Tico Torres, David Bryan, and also estranged guitarist Sambora.

Whether Richie will take the Ice Bucket Challenge remains to be seen, but if anything it might be the crucial first step towards repairing Jon and Richie's working relationship, and bring the guitarist back to the band.

Sambora left the group abruptly early last year at the start of the band's latest world tour in support of the album What About Now.
