dude musiciano, i dont know if I can properly use vowels and do this... I could do it using an Oooh and Aaah vowel probably, or do you want me to add the G's and stuff to make it Gahhhh and Dahhh Dooo Gooo etc...
tell you what, i'll just make a recording, you let me know if I did it right
Give me a minute and I'll post
