Link To Node's OG Group Homepage

Hello ive been struggling with this for a few weeks and have to ask before i go mad. Im trying to create a breadcrumb on an OG Content Content Type and have it link to the node's og group homepage. The title is no problem but the link (url) seems to be for me. All help appreciated thanks.

Title
places
%node:og_group_ref

Path
places
??????????????

I dont see anything that would create the link. Do i have to add a 2nd Context to the Page? I have tried that and failed quite miserably.

thanks
