Ambulances Institute (Live) Institute â?? Ambulances (Live Acoustic) I just heard this live acoustic version and I must say, sounds great! I did all this best with the acoustic. Please listen to the acoustic version before giving me a rating, I think you might find it works well. I'm about 90% sure this is correct. Thanks!
