Okay we got it done now and I must say it was a lot of fun even though for me it wasn't probably as exciting as it would've been if I hadn't known anybody in advance: as it is,
Pitch was the only one whose voice I hadn't heard previously.
In the end I was Éowyn,
Pitch Faramir,
Legate the Warden,
Greenie the Eagle and
Lommy the narrator (assuming I didn't get the sisters' voices mixed up), and everybody did a great job. And we didn't get it recorded because all of us are quite new to Skype and didn't bother to go through all the trouble.
I'll have to leave now, just thought I'd share this with you.
And we'll have to do more of these, really.
