Disney DVD Question

[Nice Marmot]

Can anyone tell me if Disney's "Lambert the Sheepish Lion", "Ferdinand The Bull", & "Peter & The Wolf" can be found on DVD? I am adding essential (at least to me) Disney to my collection & consider these 3 essential.

Looking on Amazon, "Peter & The Wolf" is the only one I see on DVD. It doen't look like Disney Though.
