I am a Beatlemaniac too! They had me the very first time I heard them on KRLA radio in Cali, "I Saw Her Standing There".....my heart still beats faster whenever hear anything Beatle. I just saw Ringo in concert with his All Star Band in Or. He really likes to showcase other performers and it seems they all have a blast while on his tour.
I have a stairway / hall that we have made into our Beatle Gallery. I framed all my original Beatle LPs, ragged covers from carring them with me at all times. Also a poster I got at Capt Records on the anniversary of Johns death. It was a candle lite affair. Every ticket and piece of memorbilia I have from childhood. I never tire of walking down those stairs and singing a little "I Want To Hold Your Hand"
As far as getting an autograph, that would be cool but from what I understand Ringo does not give out his autograph unless it is to support his charity The Lotus Foundation. I could be wrong but that is what I heard from an art dealer selling is paintings. I got the Postcards from the Boys too, Adorable.
Hope it works out for you but even just a brush with anything Beatles is worth daydreaming about. Peace and Love
