Regex help for MP3 name

Does anyone like to help me with some regex definition for clipping all characters before the usual 01, 02, 03.. numeration of MP3s. For example
"the greatest hits of - CD1 - 01. interpreter - songtitle" would be shortened to "01. interpreter - songtitle".


Sorry, there is already a solution in one if the rename threads, which i found after some search:

Rename REGEXP PATTERN="(.)(_|.| )(.)(.)(.*)#" TO="\1 \3\4\5"


Ooops, it should read @nodeselect
Rename REGEXP PATTERN="(.) - (.) - (.*)" TO "\2 - \3"
