Turner has some rare insight into the situation given his work with both Deep Purple - he recorded 1990's "Slaves And Masters" with the group during his three-year tenure with the band - and his years with guitarist Ritchie Blackmore in Rainbow.

The vocalist is sharing his thoughts on the April 8 event at New York's Barclays Center that sees Deep Purple's current lineup refusing to perform with former members including Blackmore - who has now decided not to attend.

"If he comes, Ian Gillan and the rest of the band won't come," Turner tells Rock Overdose. "If you ask me, they're acting like children and it's a mess and a shameful situation. It's terrible that it happened. For me, it shows you exactly what is happening over there. That these people don't know how to grow up and be friends. Just stop the bullsh*t. It's a shame and it makes a circus out of the whole thing.

"I made a statement on my Facebook that describes how I feel about the Rock and Roll Hall of Shame, as I call it. They have no idea who is who, what is what. It's a Hollywood event, and it really has not much to do with Rock and Roll anymore. It's more of a celebrity event."
