string methods (warning, newbie)

[anthonyberet]

Is there a string mething to return only the alpha characters of a string?
eg 'The Beatles - help - 03 - Ticket to ride', would be 
'TheBeatlesTickettoride'

If not then how best to approach this?
I have some complicated plan to cut the string into individual 
characters and then concatenate a new string with the ones that return 
true with the .isalpha string method.

Is there an easier way?
