Want to buy tickets but can no longer access old email address

[Vectrex]

I am hoping to try and get a ticket for my brother who is not very computer savvy, but not so sure I'll be able to.  The thing is when I registered his details several years ago I used my secondary email address.  I  closed down that email account a couple of years ago due to suspicious activity and stack loads of spam/junk mail being sent to it.  

I checked and see that that email address is still registered with my brother's details.  But if I manage to get through to the payment details for tickets today, can I enter a different email address?  Or will I still need to enter that old closed email address?  And if so, can I then email Glastonbury Registrations afterwards to advise them of a different email address?

 

Thanks for any advice.

I got coach tickets for friends and they sent the confirmation email to my address as I put mine in. Probably worth trying and then messaging see tickets to change.
