Thanks, I read the interview today. Al doesn't exactly go far in terms of asserting the band as good musicians. A couple of times he mentions that they weren't very good and gives more credence to The Wrecking Crew playing on their mid 60's songs. He does give some praise to Carl though for his guitar playing. They don't seem to have the interview online, but here's the link to the issue:
