Urgent Return of Documents- Will I get my old BRP card back?

I recently applied for a new Biometrics Card in my married name (I submitted my Biometrics Information at the post office on June 11th.) So far I have not heard anything from UK Visas and Immigration. I have a holiday coming up and I am starting to get nervous that my new card will not arrive on time.

I was just wondering, if I were to fill in the online form for the urgent return of my documents, would I also get my old biometrics card (the one that's in my maiden name) back? I'm assuming that I wouldn't be allowed back into the country without a biometrics card.

All of my previous visa applications came back in less than a month, so I'm surprised that it's taking them this long to process a simple name change.
