No Hay Cama Pa' Tanta Gente

I have several doubts with this vinyl: there is no reference to a country, so I write down "Central America" although it could be a copy of Puerto Rico or the US. There is an artist: [a7070937], but I am not sure I should add this disc to that artist, and the last question is if this "Combo Records" label is the same as [l124351].
