Dave, I fear there is some overlap between The Voice type singing and DP, it's probably fair to say that Glenn Hughes invented it long before Mariah Carey and Whitney Houston!
....
See, now you even have a reason to despise DP! 
I believe anyone singing/squealing "Georgia on my mind" like Glenn did here (my, it must have been good coke on that day!), would win The Voice hands down, don't you?
That's awful but not normal for DP.
I hate the nauseating melisma of "Whiney" Houston and Mariah Carey. That's bad enough, made worse for me by the yokels in the audience who whoop and holler when someone stretches a one-syllable word into a dozen syllables. What I'm talking about on The Voice is all that and more. You see these promos where the contestants are in a "sing-off" where the object is to yowl and wail as long and loud as possible. And while the show is allegedly about voices, it's complete with elaborate stage productions. Which is fitting, I suppose, since the voices are so wretched.
