much as it is a good song and i love it, i don't think it is suitable for aled's voice for the following reasons:
1. The song mentioned, is for an operatic voice, and i don't think aled's voice is strong enough for this song, I will go further in saying has aled has himself stated that this is the case.
2. The song is mainly in italian, and i don't know aled's level of italian, i do appreciate however, he has sung french songs before now.
3. The final chorus, when the song is about to end, finishes on top A, for a male it is the A above middle C and for a soprano, is is the A above that. They then have to hold on to this note until the last semi-beat of the song. With this in mind, although aled can reach that A quite nicely, i don't think he can hold on to that note, although he did do so in the Pi Jesu for his first album.
I hate to disagree on this, but for the reasons mentioned above, i don't feel the song is suitable for aled's voice.
