The Singing Bus Driver

To get home from HDB Hub, I usually take the feeder service. Occasionally, I'll bump into this bus driver who loves to sing. It's usually in the late evenings & I like to sit in the seat just behind the driver's. Usually he'll start humming away once the bus takes off, singing those songs in the 50's-70's.. I wonder if the other commuters find him entertaining or irritating.. Personally I kind of enjoy it. His voice is not fantastic, very nasal in fact, but not repulsive.. Well, just met him again tonight so decide to make a note of it. I'm glad he puts so much pleasure in what he does :)
