Mark, keep in mind that our audiences do not expect us to sound exactly like the original recording or artists - they expect us to sound like US!
Yes, thanks for reminding me of that. As Popeye said..."I am, what I am, what I am!"
You did a great job with this and I'm fairly confident most audiences would give you high marks.
And that remark puts you right up there in my book of "peer recognition V.I.P Persons." I think I said somewhere else...the only real rating of your music performance comes from your peers. You could be delusional thinking you're another Bobby Darin, the audience will always be polite and clap to whatever you play, but the feedback from your musically trained peers is what counts!
BUT, no one here hasn't really arrived until they've received an Academy Award. In this case the AA being the "clapping hands" from the Godfather....Donnie!
