Yes, he had a talent for not only composing catchy tunes (with great 'hooks') but was the reason their Harmonies were exquisite.
I went to the Mid-Summers Day Bash at the Old Wembley in 1975 the line-up was very weighted towards American bands. But a very memorable day, blazing sunshine and loads of American Pussy
The Eagles were amazing but they also had Jackson Browne on Piano and Organ that day and performed 3 of his songs...
The Beach Boys came on and TOTALLY Blew the Place Apart ... I mean just remembering it now and I get Goosey Bumps!
Elton John (who had a very strong backing band) came on at about 7:30pm(ish).. He had just released a Dble Album 'Captain Fantastic And The Dirt Brown Cowboy', He opened with Funeral For a Friend (Amazing song) But then went straight into songs from the new album which the majority didn't seem to know... by 8:30pm people were leaving in their droves including me and my mates and Some Very Nice Tanned Chicks from California....
We showed them London

... I remember waking up in their Hotel Room with the Hangover of a Lifetime....
