Me favourite Groove-y Salsa song

I love to groove to this:

Unfortunately, this is the 1st time that I can't find the name of the song(by Joe Cuba Sextette) .

If you know the name, please please let me know. I really appreciate it. Gracias in advance.

Me found the name from a good samaritan. The title is A Las Seis (en ingles es 'At 6')
