Mario: thank you so much. What more can a songwriter ever expect than that kind of glowing review? especially as it comes from someone as good a musician as you. Thanks! :-)

Nigel: thank you! I've just edited it, as you suggested. One question: how do you know exactly which frequency to roll off, etc.? You went straight for the 130Hz and, to my ears (when I went to edit it), it made a massive difference. How does one learn to know exactly where to go, frequency-wise, when one wants to edit a track like this? Thanks!!!
