Oldest recording in your collection

[Triton4]

Which is the oldest original album or song in your collection (I mean the original LP, Cassette, or Audio CD recording & not a revised or remastered version)?

I have the album ABBA (by ABBA), my parents bought when I was 3 yrs. old, i.e. 1985 (although the first ABBA album came out in 1975)
