I found this out in work while skiving . .er I mean, trying to concentrate!
Spotify is a client you install that streams music, for free, in exchange for the odd advert. http://www.spotify.com
The La's are on there- the original album, BBC Sessions, the Deluxe edition, the There She Goes EP
Interestingly enough they also show up on "Dad Can't Sing! Classic songs for Dad to destroy" (John Leckie TSG) and "Music for Dad" (regular TSG). And some folky all-acoustic comp has Looking Glass.
Fun!
