BLS? Lol. IF ur talking about ambulances in 1979..... That's ok. Nobody pays attention to us. It's kinda good bc we would prolly be in a whole lot of trouble if they did.
If you don't want to listen to the 'lead-up' (though it's kind of cool) forward to the two minute mark to jump to the start of the music (still some talking over the start of the song tho).
