When I notice the funny little things singers do with their voices between lines...

[Knuckles]

it really distracts me.

Examples:

Prince's "Dooo Ooops"
Michael Jackson's "Uhhh Uhhh"
David Lee Roth's "Yooooow's"
Billy Idol's "Oooww's"

name some others

[Drederick Tatum]

Rick James is the king of this.

[paul jones]

Mark E Smith of The Fall has done lots of fill-ins between vocals,usually an 'AH' at the end of a word or percussive noises

[DipDipDive]

Rick James is the king of this.

DO YA DO YA DO YA DO YA DO YA

[DipDipDive]

BTW I disagree. James Brown is the king and Al Green is the heir apparent.

[hitmonlee]

christina aguilera does a little "HA" at the end of a phrase sometimes
usually found in live performances, its sort of punctuates the end of that phrase for her.

[Caribou]

Freddy Mercury's "Skibideebop. Skeebeebopbaabop!"

He never did this before the 80's.

[Drederick Tatum]

James Brown is the king

I'd agree with you but halfway through his career that's all he did. seemed that there were no actual lyrics. just screams and calls to hit him...which was awesome.

[DipDipDive]

*ahem*

I seem to have completely forgotten the UH of Zach De La Rocha.

[Bob]

i thought i was gonna be all clever by noticing that james brown was nothing BUT funny little things but i guess it was common knowledge

[Mr.Pink]

I intitially thought you meant their breathing... if you ever notice the breaths they take between lines, they start to over-ride the main vocals...try it sometime, its especially effective with talented solo singers and news anchormen/women.

James Hetfield with the "errahhhh" after every sentence he sings.

"Back in the womb it's much too realerrrrahhh"
