1 getting Tesla — bet he crashes! (3,7)

I believe the answer is:

the beatles

'1' is the definition.
I know nothing about this answer so I can't judge whether this works.

'tesla bet he crashes' is the wordplay.
'crashes' indicates anagramming the letters.
'tesla'+'bet'+'he'='teslabethe'
'teslabethe' is an anagram of 'THE BEATLES'.

'getting' is the link.

(Another definition for the beatles that I've seen is " Group".)

I've seen this clue in The Guardian.
