A guy friend of mine squeezed my hand when we were holding hands? Does that mean he likes me?

This actually happened in a choir concert, the tradition is that my choir holds hands when we sing and then drop hands at the end of the song. My guy friend and I stand next to each other so we always hold hands during a song. At the end of a few songs he squeezed my hand and then didn't drop hands when we were supposed to. This happened a few times during the concert and his hands always get really hot whenever we singing, whether it be from body heat or nerves... I'm not sure. Between songs he also is usually the one to grab my hand before I get a chance to take his too. Is there a chance he likes me? Or is he just caught in the moment of the song? I'm really curious to see if we could be more than friends
