"I Believe in Everything" is a song by John Entwistle.

The song also appears on Entwistle's debut solo album, Smash Your Head Against the Wall.

When Entwistle was asked about the song in comparison to the rest of the album, he said: I've been saying a lot of stuff that I didn't really believe in.

So I wrote a number that touches on reincarnation, then goes into the absurd, with Father Christmas and the whole bit and right at the end just to prevent the heads from thinking that I did believe in everything like I was saying, 'cause they always seem to believe that you actually believe in your own words.

[1]The song ends with a chorus of "Rudolph the Red-Nosed Reindeer".
