level best (for bedtime)
said the whale
call me anytime you need to
if you've got a girlfriend
i'll be on the line doing my level best
i'll scream with all my might
'cause it's my level best
discussing male privilege
if it breaks me up inside
tell me that you loved her
i will catch the next flight for any country
i will risk it all to do my level best
i'd fly the plane myself and do my level best
if you need a million borrowed by tomorrow
i would rob a bank to do my level best
