Who buys the beer ...?

Knightmare, Chris, Cam, Karl, and Ross are sitting at the bar in Zaux's Tavern and Billiards. Knightmare, being quite generous, buys a round of beer for his friends.

Seating at the bar: (from the bartender's view)

Friend 1 - Friend 2 - Knightmare - Friend 3 - Friend 4

1. Ross, who is not sitting next to Knightmare at the bar, is the immediate senior of the friend who got a Guiness.
2. The 35 year old is on the same side of Knightmare as the friend with the Sam Adams Ale, the former being nearer to Knightmare.
3. From the bartender's view, the youngest friend is next to the left of Cam.
4. Chris, who had a Murphy's Irish Amber, is farther right in the seating than the friend aged 45.
5. The friend in position 2 is older than friend 1.
6. Karl is one of Knightmare's friends at the bar.
7. One of the friends is 30 years of age, and another is 50.
8. One of the friends had Indian Pale Ale.


Can you tell which friend sat in which position at the bar? ... how old is each?... and what beer each enjoyed?
