How do i work on my singing when i have never had vocal lessons?

i am in a conservatory theater program and when i tried out i had no idea i was going to have to sing. we did all the training and then the director told us that we were going to be in a musical, which no one had heard about. The other 8 actors all have singing training, but i do not. and the character i have been cast as has like 2 solos and one duet. she based this off of my audition song, which was "I wanna be like you" from the jungle book, which isn't even a real song. And now i have to actually sing notes and stuff and i am definitely struggling. But i know how the music all goes now, i just am not a very good singer, but because i'm singing in a russian accent, it doesn't really matter. but i have problems staying on pitch. does anyone know any really good vocal warm-ups or anything i can do at home other than just practicing the music to help my pitch? anything at all to help my singing whatsoever would be greatly appreciated.

get a tape recorder and rec. your self as you sing. then once your done you play it back to yourself then you know if you can/can not sing. if you can't then decide if you want to go higher or lower and adjust your voice accordingly.

GOOD LUCK!

practice until your throat hurts, try to get in on some sort of chorus group or choir and just sing with your heart in it
