I see this as they are talking to someone who doesn't know Christ as their lord and savior. They are trying to led him to Christ.
Here, "So take us in... we'll show you something you won't ever forget." I think they are saying just listen to them and they'll show you Christ. With the "This life's a road, no place is home" I think they are talking about how life is unexpected, and that nothing earthly will make you happy or solve the problems life presents, cuz you'll just continue wanting more. "My heart's a hole that needs to constantly be filled with love" is saying that their heart needs Jesus, cuz he is everlasting love that won't ever stop, so he will continually fill their heart with love.
