htaccess question

I've got my vanilla installed in a subdirectory (/social) and successfully got my htaccess redirecting any traffic from ukmusic.com to ukmusic.com/social.
NEW FORUM www.ukmusic.com/social
OLD FORUM www.ukmusic.com/forum
What I also need to do is divert all the traffic from my old forum to vanilla, so divert traffic from www.ukmusic.com/forum (OLD VBULLETIN FORUM NOW GONE BUT STILL LISTED IN GOOGLE) to the new forum www.ukmusic.com/social. I've managed to do this with htaccess
Options +FollowSymLinks
RewriteEngine On
RewriteRule ^$ /social [L]
Redirect 301 /forum http://www.ukmusic.com
However here is my question, how can I get any deeper links for example www.ukmusic.com/forum/anything to redirect, as my current htaccess only does the specific www.ukmusic.com/forum and not another of that /forum's content.
for example https://www.google.co.uk/#q=site:www.ukmusic.com/forum I have over 170'000 listing in google and need to know whats the best way to do this.
PLEASE HELP ! any help appreciated

But if not, please post a link as it looked in your old forum and how it should look in your new forum.
Then call @x00 because he is the RewriteRuleRuler

Vanilla has some vbulletin and phpBB middleware to handle old threads
grep is your friend.
X00 that's helped, however still got this issue
OLD URL : http://ukmusic.com/forum/chit-chat/most-relaxing-songs-ever-39171.html
NOTE: chit-chat = catagory name in VBulletin
Current re-direct with htaccess after your edit
http://ukmusic.com/social/chit-chat/most-relaxing-songs-ever-39171.html
PAGE NOT FOUND
What the destination url actually is in Vanilla is :
http://ukmusic.com/social/discussion/39171/most-relaxing-songs-ever
This is for phpBB but it will give you the idea

grep is your friend.
if you are converting to vanilla. I would recommend using vanilla 2.1.5 instead of vanilla 2.0.x
