Any Shangri-las fans on here?

I've been listening to them a lot lately and one standout track to me is "The Train From Kansas City". The banging piano and train sounds, the harmonies and Mary's storytelling lead make it an excellent track. The girls had amazing harmony and vocals skills and what amazes me even more was that these were 15, 16 year old girls. I always think it'd interesting to hear how they'd evolve if they lasted past 1967.
