This works for the following example:

groove some-id the rest is the groove comment

syn region MMAgrooveComment matchgroup=MMAgroove start=/^groove\ze\s/ end=/$/ contains=MMAid
syn match MMAid "\%(^groove\s\+\)\@<=\zs[^[:space:]/]\+" contained

" some colors for testing
" helped point out that the whole file was matched as MMAid
hi def link MMAgroove Keyword
hi def link MMAid Identifier
hi def link MMAgrooveComment Comment

I tend in general to shy away from 'syn keyword', because it's not
usually what you want. (If 'groove' were a keyword, the second 'groove'
on the line would be highlighted.)
