The tejano traffic jam was a mixture of Bobby Pulido and Roberto Pulido y los clasicos. The actually played "Mi amor sincero" that I used to punch every time at the jukebox when Casita Jorge's was over on Elmont. It's funny to think that Bobby Pulido was inducted into the National Honor Society in high school.I have a feeling that "amor sincero" is a song done by Trio Los Panchos.
