I had to do a musical number at pretty short notice with a couple of people who can’t learn by ear, so I asked Cat to transcribe an arrangement I recorded (with a very short deadline!) Not only did she get everything done and sent to me before the deadline I gave her (despite the fact that I ended up having to send her the recording hours after the time I promised), but she ironed out some mistakes that I’d made in attempting to write a piano part without access to a piano! Thank you Cat!
