Mark and I are looking forward to talking about the new Yes album, Aurora, next week but this time, we have gone right back to the first ever Yes compilation album, Yesterdays, because we mentioned the first song on the record a couple of weeks ago, in the context of The New Age of Atlantic album.

We enjoyed listening to the 1975 release again, particularly the first and last songs. There is a bit of audio geekery and lots of enthusing about this great collection from us both.

Please do let us know what you think of Yesterdays and what's in your deadwax, of course.

• Why was this album released when it was?
• Are there any undiscovered songs on here?
• Who is actually on the record?
