Calista entertains the group

Most of the housemates spent the morning entranced by classical musician Calista playing her keyboard.

Big Brother supplied her with the instrument this morning, but she ran into trouble when trying to set it up without a critically-needed wire.

She and John went to the Diary Room to ask for the wire but came out saying hijacker Andy McNab had been "horrible" and had refused to supply it.

Undeterred, Calista tinkered around and got the keyboard working before sitting and playing to a rapt audience of Jeremy, Emilia, Jay, Victor and John. She declared: "I just feel so comfy with a keyboard."

Jeremy shoved Emilia out of the way at one point and squeezed in next to Calista for some tuition.

Victor then gave Calista advice on how to preserve her voice, telling her that the air conditioning in the house was probably having a negative effect.

However, a tired Nathan was slightly more reluctant to get out of bed and make the trip across the bedroom to join in.

Calista asked: "Come on Nathan we’ve got to give it back soon. Don’t you want to see?"
