Ex-Bon Jovi guitarist, Richie Sambora, had his turn to have a go at “Livin’ On A Prayer” at a wedding. It was his nephew’s, Shane Ahern, wedding that took place in Los Angeles, while nothing was planned. The reception’s DJ provided the guitar who was accompanied by Orianthi on vocals (who actually was peeking at her cell phone for the lyrics). In contrast with Jon, Richie didn’t see that he needed to much persuading to sing the song!
