Hi I'm new to SQL and I'm trying to figure out how I'm going to get the top 5 "bands" with most friends (userId) and this is what i have; a usertbl with userId as PK then a bandsTbl with bandId as PK then I have a table bandfriends with FK userId and bandId. 

```
bandfriends
userid | bandId
---------------
 1     | 1
 1     | 2
 1     | 3

```

Thanks!
