Madonna will close her the latest leg of her tour “Sticky and Sweet” in Sofia and will invite the Bulgarian audience to a sing-along. At the near end of her concerts, she lets the audience choose a song and have Madonna sing along with them.

After an inquiry in her largest fan forum, fans chose the song “Secret” for the audience song in Bulgaria. It’s no “secret” that Madonna likes this song a lot, and it turned out to be one of her most popular hits in Bulgaria.

So far, she’s sung this song on the request of only one audience – that of Houston, Texas (USA). Bulgarian fans will prepare special posters stating “Our request song in SECRET”!

They also started a facebook initiative “Sing with Madonna in Sofia”.
