Commercial Breaks & Beats

This is a bit of a long shot but here goes. There's a prog on at the moment called Open Garden on BBC2 where people try to get their gardens into the Yellow Book of open gardens.

After the theme tune, they play a track which sounds like long orchestral strings - 4 bars - each one alternating. They also use the track on Gamer TV on Bravo.

Is this enough for anyone to go on?

I must try to get a recording of it and possibly post it here.

Thanks in advance.
