If you can't be bothered writing the tunes out try transposing them at sight. Add two sharps, or take away two flats to get the key signature. With printed music a line note will be nicely centred on a line and a space note will neatly fill a space. Adjust your eyes to read the top of the notes and play the space above a line note, and the line that a space note is touching. This is for Bb instruments.
