What if (Broadway show) were written by (some other writing team)?

o/` *I want to be in SI-BER-I-A!
Man that I love’s in SI-BER-I-A!
Can’t wait to go to SI-BER-I-A!
Nothing but snow in SI-BER-I-A!

I like the city of Barnaul!
How would you pay for the home call?
Love with my man is in full bloom!
Thermometer frozen in each room!

Horse-team and sleigh in SI-BER-I-A!
Snowballs and play in SI-BER-I-A!
Never sun’s ray in SI-BER-I-A!
Below-zero day in SI-BER-I-A! *o/`
