There are a bunch of songs that I'd like to sing that sit just under my vocal range (the low E of the guitar range, or the D under it). I can reach these notes with some effort, but it feels forced and the volume drops dramatically. What can I do to improve matters?

Some possibilities I'm aware of:

• Warm up and practise. Yep, that'll do it I guess. I'm hoping for advice here that's more low-end specific though: particular exercises or techniques or whatever.
• Get good and drunk the night before so I look and feel (and sing) my best. Seriously, this gives me exactly the range I want, the question is how to get it reliably (and without a hangover).

I'm an instrumentalist not a singer, and not really ready to put large amounts of effort (and practising time) into this project. Is it even realistic to hope for a whole tone's worth of range extension without applying myself seriously to the problem?
