if you did he gives you a card for your pokegear that allows you to tune into the kanto radio.
Now go to the radio on your pokegear and tune it really high eventually you will find a song called poke Flute now play that song near snorlax then speak to snorlax it will wake up and attack you.
The poke flute is a hidden radio channel in the pokegear. Go to the top star and it should be a poke flute. Once you have this playing go up to snorlax click on him and he shall battle you. Be aware that he is at level fifty and is very strong. Therefore I would advise that you save before battling.
To obtain the Poke Flute in Pokemon Red version, you must rescue Mr. Fuji from the top of Pokemon Tower in Lavender Town. (Beware though, Team Rocket and Giovanni get involved.) After being rescued, Mr. Fuji will return to his house at the foot of Pokemon Tower. Visit him and he will thank you properly by giving you the Poke Flute.
Firstly you have to fix the powerplant by getting the missing machine part. After you have returned the missing part to the owner of the powerplant, go to Lavender Town. Go into the radio tower on the right. In there will be an old man. When you speak to him he will say something along the lines of "so you are the one who fixed the powerplant", and then he will give you a radio card for the Kanto region. Then, go to your PokeGear, and select the radio. Look for the Poke Flute Channel towards the right end of the radio signal. Do this when you are standing in front of Snorlax just outside Vermilion City. Then, when the pokeflute is playing, "talk" to Snorlax, he will wake up and you can battle him. He is at Level 50.

In Pokemon Crystal, to obtain the Poké Flute (which is what I assume you meant by "poke lullaby"), you need to first wake up Snorlax blocking the path on Route 11. You can do this by getting the Expansion Card from the radio station in Lavender Town and tuning your radio to the Poke Flute channel. Once Snorlax is awake, you can capture or defeat it to clear the path.
no flute can repel
Blue Flute- Awakens Pokemon Red Flute- Gets rid of infatuation Yellow Flute- Clears confusion Black Flute- Repels wild Pokemon White Flute- Attracts wild Pokemon And that's it.
Poke Flute Just a radio channel that only Kant uses Black Flute Repels wild Pokemon White Flute Attracts wild Pokemon Blue Flute Awakens a sleeping Pokemon Yellow Flute Snaps a Pokemon out of Confusion Red Flute Snaps a Pokemon out of Infatuation
The white flute I think attracts Pokemon. Later in the game you can also receive a black flute. The black flute on the other hand repels Pokemon.
There are few types of flutes you can get: blue flute: used for awakening Pokemon yellow flute: used to snap Pokemon out of confusion red flute: used to snap Pokemon out of infatuation white flute: used to lure wild Pokemon black flute: used to repel wild Pokemon These items can be used multiple times. As you see, blue flute awakens Pokemon from sleep. Hope this helps a lot.
