this leaves me with so many questions....
everything Mordgeld mentioned applies, but it could have also been due to a lot of other factors as well. video would have been a better way to evaluate this topic. there could have been a lot of factors that would set the audience against you. your looks, your stage presence, banter between songs, lack of confidence? an audience will spot a timid front man and exhibit negative behavior against him if they're nasty enough to behave that way. always try to be confident and professional while on stage.
then there's the music. it reminds me of how I sing along with Judas Priest these days and I can't hit the notes I could nail 25 years ago. you're doing fine and then you flounder, trying to find the note your searching for to end each stanza with a bang. you need the coaching he spoke of and should also see about transposing the music down a whole step and see if that helps.
good luck and that vocaroo site is kinda wack.
