Down in Tasmania
Where the devil's jaws are far too weak
To tear you away
Ooh, I wish you well
I wish you well
I wish you well
I wish you well
Oh, my Adeline
I watch your morning swim again
Oh, cold from the blue sky
Strokes from passing mopeds
My sweet Adeline
Ooh, I wish you well (my Adeline)
I wish you well
I wish you well (my Adeline)
I wish you well
And the auld triangle went jingle jangle
On the Royal Canal
My Adeline was swimming
Sweet Adeline was singing
To the tune of Royal Canal
Swim
Swim on
Swim on
Swim on
Swim
Swim on
Swim on
Swim on
And the auld triangle went jingle jangle
On the Royal Canal
My Adeline was swimming
Sweet Adeline was singing
To the tune of Royal Canal
I wish her well
I wish her well
I wish her well
I wish her well
I wish her well

Alt-J (stylised as alt-J, real name Δ) are an English indie rock band formed in 2007 in Leeds. Their lineup includes Joe Newman (guitar/lead vocals), Thom Sonny Green (drums), Gus Unger-Hamilton (keyboards/vocals), and formerly Gwilym Sainsbury (guitar/bass).
Their debut album An Awesome Wave was released in May 2012 in Europe, and in September 2012 in the United States, and won the 2012 British Mercury Prize. Sainsbury left the band in early 2014. Their second album, This Is All Yours, was released on 22 September 2014 and went straight to number one in the United Kingdom. In February 2022 the band released their fourth studio album The Dream.
The band's actual name is the triangle-shaped symbol Δ (the capital Greek letter delta). The band often makes references to triangles. "Alt-J" comes from the key sequence used to generate the symbol Δ on an Apple Mac computer: Alt+J.
