HELP ME ON SONGS PLEASE....I'm begging you!

hi, i have some instrumental songs, i read somewhere that they are playd by richie....so i wanted to know if they are really original and richie did them, i hope you know the answers:

-Little wing (its a 1:37 songs and have only acoustic solo guitar without voice)

-Mr. sambo (its 5:19 and starts with a drum like WAR DRUMS!)

-Somewhere over the rainbow (its 3:28 but my version is not complet, it starts with a electric solo guitar)

-O holy night (its 2:32, i cant tell you anithing else!)

All songs except "something over the rainbow" are Richie's. I've always seen Rainbow acredited to guns n roses. It's an awesome song though.

Actually, I believe the musician who does "Somewhere Over the Rainbow" as a guitar solo is actually Steve Impelliterri (sp?).

Yes, "Somewhere Over the Rainbow" is played by Impelliteri, not Richie
