@PeteS - yeah, i get it now, it’s a common thing, singing the same way over different styles, Pete, its a corker of a Punk song, or at least a shouty rock number, it’s a real mind bender to try a shouty vocal rock line, one feels such a berk, but you if you get enough courage you might be pleasantly surprised, remember you wont be exposed, your ‘band’ will hide your modesty...
I had exactly the same issues Pete for some of my genre jumping efforts...25 to life, spitting feathers etc...some takes i sounded like axl rose, which was unnerving...
