Replace given text and variable number

In certain lines in my document I have the text 'NUMBER: ' followed by a number of variable length.

I'd like to use Find and Replace code to remove the text 'NUMBER: ' and the following number wherever it appears.

So , for example the lines

SEAL - FLY LIKE AN EAGLE
126730BX320 NUMBER: 9067

SOUL FOR REAL - EVERY LITTLE THING I DO
166044BX90 NUMBER: 58453393

SPACEHOG - IN THE MEANTIME
159298BX192 NUMBER: 68229

ASWAD - DON`T TURN AROUND
27947BX111


would become

SEAL - FLY LIKE AN EAGLE
126730BX320

SOUL FOR REAL - EVERY LITTLE THING I DO
166044BX90

SPACEHOG - IN THE MEANTIME
159298BX192

ASWAD - DON`T TURN AROUND
27947BX111


Can someone suggest some code to satisfy this?

I'll attach a sample file.


Grateful for any advice.
