How do you say "to be there in person"?

[Clang]

Hello all,
I'm from italy, trying to improve my real life English. I remember an expression used (for instance) to say that you wish you were there in person. Well, I don't quite remember the expression, it's just over the tip of my tongue!
I seem to remember there were words like "skin" "bones" or "flesh", just I can't recall in what order.

Can someone lend a hand of help? Thank you

To be somewhere in the flesh?

. . . , it's just over the tip of my tongue!

Say,

It's on the tip of my tongue.
