I have very kindly been sent a breakdown in English of the conversation that takes place on the Japanese show that Lena appeared on after she sang 'Personality'.  This was sent to me by my new friend juliePYG.

The male singer's name Kenji Sawada, and he is called Julie.

So in this video, Kenji is calling himself Julie.

[Julie] Lena is a quite young,

but she is performing as a worldwide entertainer

acting with many big stars like Frank Sinatra, Liza Minnelli, and so on.

Today she is doing so with Julie(me)!

By the way, Lena, do you like Frank Sinatra?

[Lena] hum hun

[Julie] How about Liza Minnelli?

[Lena] hum hun

[Julie] Well....how about Julie(me)?

[Lena] hum hun

[Julie] Oh, Yeah!, you're cute! Well, I ask you some questions.

What parts of me do you like? Julie's body shape?

[Lena] hum hun

[Julie] Oh, good. Well how about my face?

[Lena] hum hun

[Julie] Good, how about mole?

[Lena] hum hun

[Julie] Well, who do you like the best of three persons,

Frank Sinatra, Liza Minnelli, and Julie(me)?

[Lena] Julie.

[Julie] Wow! Really?

[Lena] Julie Andrews!

[Julie] What?

[Lena] Julie Andrews!

[Julie] That Julie is another foreign woman! Leave me alone! (He gets sulky.ha-ha)
